0 Replies and 229 Views Wheel & Tire limits  229  0 Started by  Grintch Why do we need both wheel size and tire size limits  Isn't a tire size limit enough Especially as the wheel size limits are hit and miss.  In STU, the tire is limited to 265 or 285mm and the wheel 'limited' to 11 (recommended maximum wheel for a typical 285 tire is 11', for a 265 only 10.5').  STR & STX both have a max wheel size of 9', but they have different max tires sizes (255 vs 265).  And the STX (& STH) max tire size is 9' which is generally the absolute min...

2 Replies and 28644 Views SEB did you mean to leave loophole for motorcycle powered cars in SM?  28644  2 Started by  Der Wankel Did the SEB mean to leave a loophole for motorcycle powered cars in Street Modified classes   The new rules state- Engine block (or housings of rotary engines) must be a production unit that can be sourced from a production automobile. Any block that is not sourced from a car of the same brand will be assessed a 150-lb. weight adjustment in addition to all weight calculations in Appendix A.   Radical holds many production car track records and the SR3 is powered by a Suzuki Haya...

1 Replies and 27230 Views Calling STS Miata folk! How do I do this to my car?  27230  1 Started by  91stanza Hello all! I have been slowly putting together an STS Miata, and I have run into some confusing things. I was wondering if someone could tell me how they did an STS-legal radio delete on their car. I'm not really sure what an OEM Miata dash without a radio looks like, but I keep reading about people who convert their cars to the base model and remove the radio and speakers. Can this be done with an aftermarket blocking plate

1 Replies and 18937 Views Any update to SM engine swap rule?  18937  1 Started by  Greg Sharpe I had heard rumors that the SEB had been approached about allowing SM engine swaps to come from alternate manufacturers, ie: an E30 with an SR20DET, reflecting current trends in the street car community. With the LS nation trying to take over every engine bay in existence, and the 2JZ crowd attempting to negatively affect F:R balance of any car they get their hands on, it's my observation that there are many cars on the road who could conceivably find a well matched home in SM wit...

0 Replies and 1249 Views Disabling Airbag  1249  0 Started by  Alex I can see in the rules that street touring vehicles are allowed to use any steering wheel, including replacing airbag equipped wheels with non-airbag equipped wheels. Would this open up street touring cars to be able to disable the airbag in their steering wheel

0 Replies and 1544 Views STR: S2000 Hardtop  1544  0 Started by  Eric Lehnen Hi all,   New to SCCA, and the forums. I recently bought an s2000 and working on it this winter to enter into some STR events this year. I also plan on adding a roll bar/seats/harness. For added security, I want to add a hardtop as well. However, a used OEM hardtop is $$$. I can buy a new aftermarket hardtop that is half as expensive. My question is, the rulebook for STR does not state anything specifically about hardtops for STR. Does this mean any non-OE hardtop can be used Second que...

1 Replies and 18783 Views Electric water pump allowed?  18783  1 Started by  cstallings I recently acquired an 04 MINI Cooper S. The previous owner had an electric water pump installed. I'm thinking this would preclude the car from STX competition as I can't find a specific allowance in the rulebook. Am I correct in thinking the electric water pump would bump this car to DSP

1 Replies and 19524 Views BMW M2 in STU?  19524  1 Started by  Fault Bucket Asking to confirm the answer that I believe to be true. The classing page for STU in the rule book has a catch-all rule at the end: “Catch-all”: Sedans & Coupes NOC (nonsports-car-based; 4-seat minimum; over 5.1L normally aspirated or 2.0L to 3.1L forced induction). The BMW M2 would fit within this catch-all rule, correct Thanks

3 Replies and 19956 Views STS, Swap Transmissions  19956  3 Started by  AjHawk First off, there seems to an issue with the Search bar, it errors every time i try to search for something. I wanted to know about the STS Class, pertaining to swapping a transmission. I have read 'Street Touring' in the rule book multiple times and cant come up with anything about transmissions. The car is a 1993 Civic DX, the transmission is from a 1997 Civic EX. Both cars are in Appendix A under 'STS'. Without a rule prohibiting it, could I swap in the transmission from the 97 EX Or is ther...

7 Replies and 19027 Views STU addition - Solstice GXP?  19027  7 Started by  Fault Bucket I haven't paid too much attention, but has there been any discussion of perhaps making the Solstice GXP eligible for STU Some other AS/ASP brethren have been added lately, and with a tire width limit of 285 I don't see it as an overdog. If I don't hear any negative feedback on the idea I'll post up a letter. Thanks! Chris

3 Replies and 20030 Views Dual Clutch transmissions (VW, etc) - reflash legality  20030  3 Started by  gtitronic I'm considering a (dual clutch automated manual) DSG transmission equipped car like the VW GTI. Mitsubishi also has their SST dual-clutch on the 08 Ralliart and EVO X, and I'm sure there are others out there. Based on a quick read of the Street Touring rule book, it looks like there is no provision to modify or reflash the factory transmission control unit (TCU) in any way. I'd assume my interpretation is correct, but let me know if you disagree. The closest things I see are: 14.10 B. Origi...

I had several potential transport options that seemed moderately likely, and a couple of long shot ideas, none of which panned/priced out. :( Early on SSM seemed to have had 8 folks, and now it's down to 7. Soon it will be 6 and no 2nd place tire, unless someone presently registered want's to lend a seat. I'll be happy to donate to tire/consumable costs of course... Mail me at: gus.heck &...
