This is a rought guide on setups for the FD model RX-7. You will need to tinker with the setups until you find one that suits YOUR driving style.

Dan - Those are from Pettit Racing in the States ...correct?

I had my FD checked out in May and used the long track set-up. Very happy with it :)

I think they are the Pettit settings, but everyone seems to quote the same figures so a bit hard to tell.

are these figures in degrees?

What difference can I expect between the different setups? Ie will long track set up give less tyre wear and less oversteer then a short track setup etc etc?

Are these figures not for a totally std FD ?
ie. you can only use them as a base map if you have aftermarket wheels tyres and suspension

those std settings won\'t be suitable on all cars, as Fish says you will have to start from there and tinker.

Ah!!
Well mine aint standard for sure, MS01 17\'s and a GAB coil over set up thats lower then a snakes belly.

I have had it tracked to the short track set up and although I havent driven it since for any length of time the car has been transformed. Tracking was not only a mile out, it was also different on all four corners! SO it has to be said that anything would be better then how it was. The only thing I would say is I think the camber settings for the front are a little over the top, might have to get that pulled back a little before the front tyres wear the insides to nothing!

Anyone knows how to transform that 1/16" toe-in to degrees ?
I dont have the slightest idea how much degrees that is and local alignment shop does the alignment in degrees only.

Nevermind, found it on the web :)
I\'ll post it here for anyone else needing it:

Refer to the chart below to convert to minutes or degrees of toe. There are 60 minutes to one degree. A good rule of thumb is 1/16 inch toe in per wheel front and 1/8 inch toe in per wheel rear for a car doing autocrosses/time trials.

NOTE: This chart is based on a toe gauge that is 24 inches wide and will NOT be accurate for other WIDTHs.

Toe measurement 1/16 inch or 0.0625 inch = Toe angle 8.95251minutes
Toe measurement 1/8 inch or 0.125 inch = Toe angle 17.9051 minutes
Toe measurement 3/16 inch or 0.1875 inch = Toe angle 26.8578 minutes
Toe measurement Ľ inch or 0.25 inch = Toe angle 35.8106 minutes
Toe measurement 5/16 inch or 0.3125 inch = Toe angle 44.7638 minutes
Toe measurement 3/8 inch or 0.375 inch = Toe angle 53.7172 minutes
Toe measurement 7/16 inch or 0.4375 inch = Toe angle 1.04452 degrees
Toe measurement ˝ inch or 0.5 inch = Toe angle 1.19375 degrees
Toe measurement 9/16 inch or 0.5625 inch = Toe angle 1.343 degrees
Toe measurement 5/8 inch or 0.625 inch = Toe angle 1.49225 degrees
Toe measurement 11/16 inch or 0.6875 inch = Toe angle 1.64152 degrees
Toe measurement ľ inch or 0.75 inch = Toe angle 1.79079 degrees
Toe measurement 13/16 inch or 0.8125 inch = Toe angle 1.94008 degrees
Toe measurement 7/8 inch or 0.875 inch = Toe angle 2.08938 degrees
Toe measurement 15/16 inch or 0.9375 inch = Toe angle 2.23869 degrees
Toe measurement 1 inch = Toe angle 2.38802 degrees

Here is a little excel spreadsheet that can calculate the sizes.

Thanks Fish,

Sorry for being ultra-dense, but what do I do now ? In your chart of alignment settings, there are differences in the adjustment settings for 16", 17" and 18".

I need to work out what my starting point is for 19". Shall I just extrapolate the numbers and try from there, or use the numbers for 18\'s ?

Cheers, Craig

I took my rx over to Steve, he runs the RX-8 racing team, he has his own business as well, doing TVR\'s etc. He set my 4 wheel allinement and Tein suspension up. I run 18\'s. No under/oversteer spot on. We were at Bedford track the next weekend and being a rading driver himself i let him take me out in my rex to test the set up. Perfect. I never knew a rex could stick like that to a track wonderful time.
He will set your car up give him a ring. But remember every car is different so there is no perfect calculation. My view was i will get the best to set it up and approve it to his standards, which are no less than perfect, then i have one less thing to think about on track or up the strip. His phone number is 01327 878425.
Steve GUGLIELMI Motorsport Ltd. Pop his name into Google see how many pages you get up, enough said. Respect.:wave
Forgot to say -- he sorted out my track and road settings for my suspension. It had been set up for drifting in japan and not put back properly for road use. Back end don\'t move now.:cool

Top thread, especially as having my car set up for when I hit the Ring will be mega.
Phoned The Guglielmi establishment but waiting for a call back (sure they are in high demand).
Can anyone recommend a laser alignment place either close to Milton Keynes or Durham (yeah, like there are garages up here!) that\'s open on a Saturday ?

I only have 5 or so weeks to get my Rex sorted before I put it to maximum use !!!

Cheers,

Mart.

Just a quick one to say that this was a fantastic help in setting the car up.

I had the car set to the long track setting but put -1 degree camber on the front instead of the 0.9, and then proceeded up the A483 to liverpool to see the other half........ Handles like a go-kart  :D  :D although there was one instance of: :3gears-lh but that was because of some nonce in a Civic type R...... needless to say he wasn\'t around for long!!!

If anyone wants to test the handeling of their car and can get to the A483 without a major detore, do it its a blinding road especialy the Newtown - Bilth Wells section :yes !!

Cheers, you\'ve helped me out again guys
