FD 18 x 10 wheels for track

Hi guys !

I know there has been many threads about the wheel fitment and offset, but it's hard to tell if those discussion were for track car or street cars, which can have vastly different requirements.

So for those of you who have used 18 x 10" wheels for track duty. What offset will work?
Assuming aftermarket coilover shocks are installed, and fender rolling is non-issue like most tracked FD.

I've been told 18 x 10" +52 or +50 is a proven setup. Is this correct?
At this width is there any touching of body/fender/frame at full lock?
Are there any clearance issues front or back?
Are there any height limitations?

The idea is to run 265/35/18 tires with 18 x 10" all around.

*Yes i know you can run it on 18 x 9.5, but i would like to use the 10" wheel for better sidewall control of the tire.

Thanks !

Randy

With those tires the +50 is probably OL.

I run 285/30/18 on that size wheel, and on the rear a 5mm spacer is required to keep the tires of the aftermarket trailing arms.

The 'offset' term is such a pain, I wish we could refer just to backspacing, which does not change with wheel width.

BTW, you will probably want to roll the lip down on the wheel arches.

I like backspace measurements to tell if the wheel will fit on the car.

For example, we know 7.5" backspace fits a wheel comfortably with coilovers on an FD.

I like offset measurements to tell me if the tire will fit on the car.

For example we know that with moderate camber (2-3 degrees front, 1-2 degrees rear) +45 offset will fit the widest tire possible on an FD (295 fender lips rolled under/coilovers) so every 1mm from 45 offset can fit 2mm less tire width.

What size wheel and offset are you running jk?

I believe he stated he runs the standard FD track fitment of 285mm wide tires on 18x10 +50 front and and back (except with 5mm spacer for 18x10 +45 rear as he has aftermarket trailing arms that take up a bit more space).

The 18x10 with 265 tire you want to run will fit with an offset between +50 to +35 with coilovers and a fender roll.


Before my current 18x11 +45 w/ 295s (requires shortened front swaybar for full steering lock) I ran 18x10.5 +38 w/ 265s.

The rear trailing arms are Improved Racing (no longer available) and are offset for clearance. Even so, there was enough rubbing to warrant the 5mm spacer.

There's a 5mm spacer on the front as well, but that is just to deal with a rotor hat to wheel hub flange clearance issue.

The Forgestar wheels have ginormous hub flanges that do not clear the bolts on my Coleman rotor hats by about 3mm.

Found the password to my old account !

I decided to get a set of 18 x 10.5 +30 offset Enkei NT03M.
Front fender will be replaced with Feed, and rear fender is already rolled.
Tire will be 285/30/18 TD

Let's hope this work well.

Will keep you guys updated on the final fitment !

I was oggling those as well as I love that wheel and they were close enough to pick up.

Those 18x10.5 +33 would fit my rolled fender FD with 265s.

You are going to have to do a big pull in the rear to get 285s to fit in back.

Go slow with heat and pull the fender out and then contour the lip up instead of the trying to just roll the lip up and you should be able to get it without dimpling the fender above the wheel well.

I ran 265/35-18 Ventus TDs on my 18x10.5 +38 and I prefer the softish TD sidewall slightly stretched like this to provide better steering response/feedback.

My next set of 295 TDs on 18x11 +45 felt a little lazier than the 265s.

You can always start with 265 TD on that 18x10.5 +33 stock rolled rear and rolled/pulled front and work into the 285 set with pulled rear and wide fender front.
