Let me first say sorry for this stupid question but I have googled it and not found an answer. Is it legal to run the same stock size and offset wheels as the rear wheels on the front of my S2K in BS? Yes I would like to run a square setup. The SCCA rules don't seem to say one way or another. Thanks for any input. Nicholas

 

No, must run OEM front sized wheels with a small offset tolerance (6-7mm?). See the auto-x sticky for more info...

https://www.s2ki.com/s2000/topic/172...s-information/

The rules state the following...

"13.4 WHEELS
Any type wheel may be used provided it complies with the following: it
is the same width and diameter as standard and as installed (including
wheel spacers if applicable) it does not have an offset more than ±¼”
(±6.35mm) from a standard wheel for the car. The resultant change in
track dimensions is allowed. Tire pressure monitoring sensors may be
removed.
Wheel spacers are permitted, provided the resultant combination complies
with the offset requirements of this section. Wheel studs, lug nuts,
valve stems (including pressure-relief types), and/or bolt length may be
changed.
Vehicles equipped with rims having metric specifications may use alternate
rims as determined by using the following procedure:
Diameter: converting the metric measurement to inches and using
the nearest smaller inch diameter rim.
Width: converting the metric measurement to inches and using the
nearest smaller ½” (12.7mm) width rim. Offset and track must still
comply with the requirements of this section."

Thanks Marc! Then what size tires are people squeezing on the fronts? Back in the day Robert Carpenter used to fit 225/45-13s on a 13"x5" rim.

 

I ran 255's on my stock 7" wheels with good results last season.
