Wheel width???

[darko32]

Hiya guys, was just wondering if anyone knew what the widest rear wheels you could fit on an rx7 and would this affect the going around corners handling at all?

Regards,

what size do you want to go to?
 
We are in the process of ordering some pretty large real wheels!!
 
Depends on the size of the arches at the back, if you want to run standard arches then you will need to find a company that will give you flexibility over the offsets, but from a rough calculation you can go up to probably an 11J with an ET30...
 
Wouldnt go to high on the front though as it ruins the feel, and unless you change the geometry of the suspension you wont be using the full width of the wheel anyway.

Actually 11j was pretty much what I wanted! What kind of modifications to the arches are you referring to? Like rolling them out? Would try and keep 9j at the front. What kind of sizes have you found work best for your track applications?

[AtomicRex]

If you run an 11J you are going to have to modify the arches, and you are going to run pretty close to the trailing arm on the suspension.
 
We were working out wheels a couple of days ago, and our current wheel is a 9J on the rear, ET29.  This has 70mm worth of clearance inboard and 5mm clearance outboard.
 
So being that I was absolutely knackered last night.....I will give you a better calculation now!
 
If you are rolling the arches you can assume you might get another 10mm clearance.
 
By adding another 2" to the wheel, you are effectively adding 1" either side.  The inboard side isn\'t an issue, however you need to move the outboard side in as you only have 15mm not 25mm.  This would mean an offset of ET39.  If you wanted to guarantee that it will fit under then maybe go in a further 5mm so you would need an offset of ET44.
 
Maybe going with a 10.5J would be a better idea?

there are plenty of kits / arch extensions out there. as for mods at allow 11J,  - attach the arch, cut out the wing and re - weld it then make sure its well sealed etc. i am running 12J 19s on the rear of mine

thanks for all the info! i find it really difficult to find those wide wheels....any ideas??

[AtomicRex]

Im getting some made at the moment....
 
What size do you want?

you will do............. there are virtually none out there! and IF you find the width you want the chances are the offset wil be way out!!
 
i had mine mande at I forged

Image are very expensive though!

Image are very expensive though!

they arent shocking. think it works out at £500 a wheel. compare that to iforge or asanti and thats very very cheap.
its all relative.......... yes they are more than most wheel brands but noone else makes 11" by 19s or 12" by 19s so these have to be custom made. thats why you pay a premium!
 
personally i would have had asanti but i couldnt justify paying £1000000 for a set lol

i have the same.  - think it was $1750 dollars a wheel plus shipping or something like that.

[AtomicRex]

I can get them a lot cheaper than this.
 
We are running this wheel this year

[jamie_supra]

are those 19" 12Js?

[AtomicRex]

Not sure what width that is....just a library picture of the wheel.
 
Will be putting up some pictures of the new wheels when they land!!
