- G Stock is where the MINI Cooper S is classed
- It's main competitors are cars such as the Toyota Celica GT, Dodge Neon, Subaru Impreza 2.5RS, BMW E30 318is, etc.
- What modifications are allowed in SCCA Stock class?
Any front sway bar, end links, and bushings may be used.
Any exhaust from behind the catalytic converter and back may be used.
Any spark plugs may be used.
Any spark plug wire may be used, including those with an in-line capacitor.
Any performance coil may be used.
Any wheel that is the same diameter, width and offset (within +/- .25 inch or about 6mm) as a factory wheel. Wheel spacers may be used to meet the offset requirement as long as the spacer is no more than .25 inch thick.
The allowable sizes for the MCS are 16x6.5 offset 48mm and 17x7 offset 48mm.
Any D.O.T. approved tire that fits on the rims stated above may be used. This includes Hoosier A3S03, R3S03, A3S04, and R3S04, Kumho V700s and V710's, Yoko A032R and Rs, and Michelin Pilot Sports. The best tire choices for the MINI Cooper S is the 215/40R16 from Hoosier (as of 1/15/04) with 205's available in both 16's and 17's. Some 225's are available, but are much taller diameters and have fitment problems.
Any air filter may be used, as long as it is the same size and shape of the original. The air filter must fit in the original air box. Running without an air filter is also allowed.
Any shock absorber with no more than two adjustments may be used. The shock must mount in the original location. On shock absorbers with adjustable spring perches, the perches must be welded in place.
- If it does not say I can, can I?
No. The rules are very specific about modifications.
- I have heard about comfort and convenience, what falls into this category?
C&C is to allow you to make modifications to your car that offer no advantage while auto crossing. Some examples of allowable C&C upgrades are-
Aftermarket stereo equipment (this does not allow the removal of the stock radio or speakers)
Driving lights, clear taillights, clear side markers, and alternate gas cap lids.
- Can I retrofit options to my car if it didn't come from the factory?
Yes. The rules state that you must change all the parts that are included with the package, such as the Premium Package. This is where the MINI has an advantage over other cars in stock class. At MINI, almost any option can be ordered separately, therefore allowing it to be added at a later date. Some less fortunate cars require major add-ons to get minor changes.
If you have any questions or corrections to what I have written, please post them here or email me at address below so that I can update the FAQ.
Thanks,
Brian Garfield

I have a follow on question for Brian Garfield or anyone else who knows: Brian in your response above you indicated allowable offsets for the 16" and 17" wheels, specifically .048 for the 17" rim.
1) Is that an allowance or the actual offset for the OE rim.
Reason I asked is I am going for a new set of wheels and have seen cautionary warnings such as "This may require trimming of the plastic fender liner lip/seam when using wheels with ET42 or lower offset" for numerous rims.
Two more questions?
2) Do you know what kind of tool and how much work it is to trim the fender liner lip/seams.
