Wheel Guide - fitting

[JoeRX]

Can anyone steer me to the correct fitting for Wheels?

Looking to get some TE37's 17", and want the fit to be spot on.

Thanks

should have said 2003 FD

It's quite subjective. Theres a wide range.

There's even a little Excel spreadsheet I got from the other forum across the pond that shows fitment specific to the fd.

And check this out

Lets see your wheels

I'm looking for some new wheels for the fd i find the stock ones to boring lol. I would like to see what other people are running for inspiration. If you could post pictures and specs et width etc that would be awesome! cheers

Thanks for this thread. I don’t want to have to roll the arches. So I know it will be 17” max. But it’s the width and offset I’m struggling on.

Actually the diameter between 17 and 18 doesn't make any difference really. You'll be at or around the same overall rolling radius.

It's the width v et that'll get you

And folding the central part of the arches return really isn't a big deal

Best fitment guide is over on RX7Club.com. If you take a look at the thread Maximum Wheel and Tire Width Fitment Guide for the FD

There's too much great info on that thread to pull it all over well, and credit to those that made those posts. There's a post on 17" vs 18" and the relative advantages/disadvantages to each as well as discussion of the tyre selection for relevant sizes and offsets as ultimately fitting a wide tyre on a super aggressive offset will cause rubbing or possible serious damage to the tyre.

I've extracted a pertinent section to help in your decision (but please read up on tyre selection as well, although as highlighted bold, this is guided towards maintaining stock rolling diameter):

Option 4: Create your own Wide Wheel Wide Tire fitment:

Because the number of wheels available in the aftermarket is endless, it is not reasonable to cover each option. This section will provide a general guide for FD width and offset for WWWT front and rear fitment.

I believe that the offset chart that is displayed in the FAQ for the FD is too conservative for people trying to fit the widest wheels and tires possible. Many FD owners have been able to successfully run wider and lower offset wheels than what is specified in the FAQ. That said I believe that the FAQ is an EXCELLENT guide for standard (read not maximum tire and wheel width) fitment. I have created a new chart of what I believe to be a more accurate representation of proper FD wheel sizing for the purpose of fitting the widest tires possible inside stock or rolled stock fenders. The lower the offset the more fender rolling will be required.

A conservative fitment is one that is in-between the offset ranges. A 9.5 +29 will work in the rear insofar as it will stick just as far out towards the fender as an 11 in +48 wheel. That said, there is no reason to run a 9.5 +29 wheel as you can easily find a better offset that does not have all the problems of fender rolling associated with it. I have included what I believe to be the ideal offset for the listed wheel width. The ideal will not require a fender roll to fit the wheel provided you have a 25 in overall diameter tire in the front and have stiffer than stock suspension. The exceptions to this rule are the 10.5 and 11 in wide rear wheel which will both require a fender roll.

FRONT
Wheel Width Offset range Ideal
10 +50 to +52 +52
9.5 +44 to +56 +48
9 +37 to +63 +45

REAR
Wheel Width Offset range Ideal
11 +48 +48
(will require fender roll)
10.5 +42 to +54 +48
(will require fender roll depending on tire size)
10 +35 to +61 +44
9.5 +29 to more than +60 +40​

Thanks for this! Fantastic thread of information.
