235 tires alone = CSP. the rest of the stuff would put you in STS just maybe... but more than likely you'll be in CSP like me because of the 235 tires

 

thaxn for the prompt reply. what does csp mean??? sts is street touring right??

 

I believe CSP is C Street Prepared. STS is Street Touring S, I also think the limit on tires for STS is 225, I could be wrong, I'm just going on memory.

 

225 is the widest tire allowed in STS.

Your 300ZX brake conversion would put you in SM I believe.

 

I thought our cars are D class in Street prepared...

 

well... i just found out what my car was under.. they stuck me in osp (open street prepared) so i'm guaranteed not to win.. but it's all good i wasn't there to try to win, i had alot of fun..thanx of all your tips guys... the tire size would have thrown me into street modified. then the brake conversion through me into OSP...

 

sorry i didnt get you PM mingo...glad you had fun...just wondering what a 2k2...245 tires...18"...FSTB..RSB..RSTB....Intake..and High-flo cat..would put me in...i know the tires are waaaay wide..but im still a little foggy on the classes.

 

you're either street prepared or osp.. but i think you're street prepared because you have stock brakes.. the displacement alone will throw u in street prepared i think.. and tires too. i tried pm-ing you but then you're in box is full. anyways.. i'm goign out next week again and i hope i do better. i learned alot today, and am very happy that i made the decision to join an autoXing event..

 

DSP D Street Prepared looks right.

Little better index than SM (Street Mod) too.

 

You would be in DSP if you went to a 225 or lower street tire you would be in STX because of the brakes. If I were you I'd get another set of S-02's they handle way better than the S-03's. The S-02's have a larger tread width {9.2"} vs the s-03's {9.0"} tread width. If you want a tire that will last much long go with the s-03. The tread rating for the s-02 is 140 while the s-03 is 220.

 

You would be in DSP also. If your tires were only 225 you would be in STX. The engine size limit for sts is 3.1L, for STX it's 5.0. I haven't heard of osp it must be a local class only.

 

yeh i think it's a local thing.. they basically made that class for this group of people that have cars built just for autocross.

 

hey Mr. Mingo..whats the next event your gonna plan to go to?...so i can try and meet up with ya..and get some visuals on how this stuff really works..my cars fixed now..heheh

 

i was thinking of going today but then i wanted my new tires mounted, that didnt' go too smooth either so i'm still rolling on my old tires.. hopefully i'll be able to run next sunday.

 

They put me in DSP, with stock tires and a few mods
