Got my rear antiroll bar kit today. Bought from a company in the states, all bits are there and it\'s a straight bolt in kit, and came with instructions which I wasn\'t expecting!

If i buy everything then the car then i am not essentially building the car myself

(i know its not necessary but its always good to have something different rather than going the tried and tested route)

Alright then smarty pants. If you want to become a little picky shiv, then if you remember we were talking about the brakes when I said the statement above was I not? And seen as though this was a very cheap kit why would I go to the trouble of making it? And I wouldn\'t know where to start with making the antiroll bar kit seen as though the car did not originally have an anti roll bar kit, and I do not want to cut and drill into the body of the car to try and get something that was not made for the car to fit.

Whereas with the brakes as what we were originally talking about, the brakes were already on the car when I got them and I have obtained the other bits from owning other cars, an elford turbo FB of which I got the front struts from.

And just to let you know I think I have worked out the best way to get FD disks and calipers onto the front of the car using all of the bearings from the FB struts. And it will certainly be  cheaper than having to buy FC hubs and disks:Thumbs-up

Also tool if you dont have anything constructive to say then don\'t say it so to not fill my thread with irrelevant replies

[Rotaryguru]

tool is correct in what he says. spend the money in the right places. that kit is pointless anyway

[kiwimazda]

Put it on. If it works or not (and by putting it on you will find out) It will look good also

Why is it pointless? Surely it will aid in the cars handling? I understand to spend the money in the right places but I can save bits here and there in things I can do then surely that is the best thing?

I won\'t be driving this car around a race track but surely an antiroll bar will help the handling on the roads? Stop it rolling?

[Grant Monkhouse]

I agree totally. This item took a serious amount of trawling through the Internet to find so it\'s going on wether it helps or hinders the car.

I\'m just amused that one minute you say you don\'t want to buy everything for the car and the next you have bought a roll bar kit.
 
I\'ve converted leaf sprung rear axles before (e.g. fitted a 4.11 LSD disc brake rear end into a KE35 Corolla to take a 3T-GTE). The sway bar won\'t add anything. There\'s much more important things to do than worry about axle tramp and body roll imho when setting up the axle.
 
It don\'t matter to me what setup you run. I offered some advice. You don\'t want it, fine. I\'ll let all the others on here who know the oldschool rotors so well step in. But don\'t post stuff on a public forum and get your knickers in a twist when someone pulls you up on it, eh?
 
E_X_I_L_E is the home of oldschool rotors

[Grant Monkhouse]

Ok Tool I thank you for the advice, any advice that I get is taken on board as I have never rebuilt a car that is older than me. I am 25. Let alone an old school rotor.

To learn things anybody must apply the theory, often learnt from the Internet, into practice and learn from there mistakes?

Would you take something for granted without going out and trying it, questioning the theory behind it?

I would prefer to convert the rear end from leaf springs to coil overs but to do that would I not need to chop and cut the chassis? As I don\'t want to cut such a rare car.

Oh I don\'t wear knickers. A jock strap is more comfy!

Wo there people ,

If you look at my own old skool RX-4 you will see that along the way I changed my mind about my project,

At one stage I was going to go the big wheel big brake route but changed my mind along the way and went for a different wheel with the same rolling radius as stock,

Point being with projects like these things change along the way and if somebody wants to alter or buy something for their own car then who are we to ridicule them,

Mr Tool not sure why you wanted to throw a hand grenade in on this thread but it\'s sure not welcome on this site :Hammer,

[Grant Monkhouse]

Thanks Clive. I don\'t want to cause arguments and I do appreciate Tools Input.

If you want to be picky then take your anti roll bar off the car(front and back) and then drive the thing(if you can),then see why we are doing the mods we are. If you build a car like this then you put everything necessary on the car while its stripped. Anti roll bars are there for a purpose, thats why we are putting the bloody thing on.
        I might point out that I put a post up a long time ago on several rotary websites asking for advice from people and got .... all from anyone in this country. Advice came from a number of experts in Australia and the States who were all enthusiastic about what me and Grant are doing and bent over backwards to give their very welcome advice. One of those bits of advice was to put a ....ing anti roll bar on the rear of the car, much the same advice I got from Mustang handling experts in the States which is why my Mustang has anti roll bars front and rear.
      We are trying to do a little bit of our own thing here and thats why I\'ve spent all day on a lathe modifying front hubs so that we can put FD calipers on the front of this car. Grants idea and my engineering expertise.When we\'ve got the setup right then I will have new hubs cnc\'d from steel.
 As for someones comment on there being lots of other things to do with a live rear axle(with leaf springs) other than put traction bars on it, well, smartarse,the floor is yours.What do you suggest, maybe an FD rear axle? Hmm, have to put the tie rods somewhere. Coil springs? Hmm, now then, we\'ll just chop a very rare car up and do that. Maybe torsion bar suspension? Or Air suspension? We are trying to keep the car as much as possible an \'Old School Car\', theres a clue in the heading that the car is under on the website. There are one or two other things that we\'ll be putting on the car that we haven\'t made, things like tyres, the odd wheel bearing, petrol, ooo, brake pads etc. I\'ve said it before and I\'ll say it again, if you haven\'t got anything to positive to say then .... right off. Oh, and this is Grants old man speaking.

[kiwimazda]

Fair play to you guys doing it YOUR WAY
I was told things that I was doing on my rx7 race car would not work by those who had not done it. Guess what, it worked and it was a winner.Same for the westy and thats getting there ,but I am not sure if we will see that out in my hands again. Time will tell.
Carry on with your work I think its brill

This will be the first and last time I respond to you Monkhouse senior. I don\'t appreciate your tone.
 
Try taking off my front and rear sway bars? What a silly comment. Besides, I only have a front sway on my RX2.
 

 
R100 to RX4 were not fitted with rear sway bars for a reason. See below stage II modifications from:
 

 
What diameter is the bar itself? What diff are you planning on running? Standard ratios show below:
 

 
The most important and basic modifications have not been covered. Urethane bushes (all available for purchase in the UK). Reset and strengthened leaf springs. Uprated shocks (or at least new ones). If you want the car to handle, you have to get the arse down. The lower the better imho. You\'ll need to reset the leaf springs (I don\'t like lowering blocks) and add extra leaves or get some reverse eye leaf springs (hard to find).
 
If you\'re a Mustang/V8 owner, I\'m sure you know what slider bars are.
 
How low you go then depends on what wheels you want to run and what will fit under the arches. What PCD are you going to use? The RX7 S3 discs you have are 4x114.3. The standard 4x110 leaves you with few options for finding wheels. You will more than likely end up with FWD offsets.
 
As you previously stated, you have chosen to run FD discs. You will need to run 17 inch wheels (you could scrape by on 16s but it will be tight and require further mods to the calipers if the wheels don\'t clear them). You further restrict your wheel options too.
 
If you want to improve the handling of the car, the biggest gains are to be made from modifying the front. See specs below and some mods that can be done with RX4 front struts (although you won\'t be using them):
 

 

 

 

 
Some major improvements can be made to the geometry see below:
 

 

 

 
Parts are available if you know where to look:
 

 
A bigger front sway bar will definitely help. Spend the money on that. The biggest improvements on the car are shown above. In all honesty, I don\'t think you\'ll notice any change from fitting the rear sway bar. And for the record, I never said don\'t fit it. I just said I don\'t think you\'ll see any real gains. I have done this conversion before and the car had immense handling with or without it.
 
To make myself clear, I never said don\'t do this or don\'t do that. Your way? Good one Brian. The REspeed parts are very good quality. I have some of their kit. I just offered an opinion. More than most people on here.
 
FD rear axles? Air suspension? Etc. More silly comments. I don\'t even know why you started going on about this.
 
As for not getting much help from the UK, what can I say. They didn\'t get many of these cars and very few people know them. But, when I do offer some advice (which you apparently want), you become rude and offensive. There\'s no need for that.
 
I think it says a lot that your club President (who owns an RX4) doesn\'t offer much advice but is clearly watching the thread and has the time to comment when E_X_I_L_E is mentioned. Where\'s the comments on the tirade of abuse from Monkhouse senior? I thought this was a family forum? And the other club has moved on from grenades (wink wink).
 
I don\'t think this site (or most other UK sites) can offer much advice on your car, which is why I don\'t spend a lot of time here. I use other sources. There are cars actively being built and modified on the other site. I have happily provided advice and parts to other RX4 owners in the UK too (you know who you are).
 
My local Mazda dealer is an enthusiast. He has an RX5 in the showroom. he has a mint restored RX4 coupe and an R100 shell he bought off VW that they had in the late 60s for corporate espionage. He also has a shed full of parts.
 
I\'m not claiming to know it all here, but I have also done a lot of research and spent time with a number of these cars. I am building one of mine atm.
 
As for the post about mph from a sticky (which noone responded to); post up a link to the sticky and provide the information you entered so it can be discussed. I can\'t say anything at this point untilI know what figures you were working from.
 
Anyway, good luck with the build Monkhouse junior.

I have removed the swaybar on my Gen1 RX7 for better handling.
 
With one fitted, you can get snap oversteer - not something I want in a 450bhp (potential) car, without one you get gradual break away under power when cornering. Better tyres and sorted shocks/springs give you much higher grip than standard and will only accentuate the above issues.
 
You mentioned previously not getting much assistance from the UK, but that doesn\'t mean you should disregard it when it does arrive - amusingly though, sometimes from people not from the UK..
 
Good luck with your build - a well sorted \'4 is a thing of beauty. :cool
