My scca solo group has one of those fire spitting FD RX-7's that runs a massive wing, and aero, and his only competition is turbo'd Honda S2000 that's about 500whp in SSM.
SSM isn't a class for the meek and mild that's for sure, but comparing time between SSM, and ASP, and looking at the resules for the last two events, it's pretty surprising. The ASP cars are very competitive in shorter tighter courses so far this year. We'll see how SSM and ASP match up on the bigger courses where the SSM cars can really stretch their legs.

I'll pm

I was only .031 off the top SSM time at the Wilmington National a couple of weeks ago. Some courses they can easily be 1+s faster than me.

I finally got the answer on the reason why... Rrrrrrrr. It's because of the damn spherical bushings they use. So it's not just the toe arms that aren't asp legal in my case, it is the rear camber arms too! That is why I could never find why the toe arms were not asp legal. So if they were made with poly bushings then I would be fine. F it, I'm doing this for fun anyway so I am not that butt hurt about it.

Lesson learned, if you want to auto cross with SCCA and not be SSM then don't get spl get the less quality spc or kinetix camber and toe kits. Also I looked at stance and they are spherical as well. This took me a few hours of reading back and forth and back and forth.

I am now even more angry Those rules. There should be a limit on how many mods you can have before going up in a class like a max of two or three.

Exactly why I would be SSM ... and I am too lazy to remove the SPL stuff just to be in a different class. Doing it for fun anyway so don't care what class they stick me in.

LOLOLOLOLOLOLOLOLOLOLOL...

One thing i learned while serving in the US submarine service is how to improvise properly! I just got off the phone with an SPL guru and he said that i am not the only one that has called about the strict SCCA rules of having metal bushings. But there is not enough interest about them for SPL to make them available but he said when i find a solution to inform them so they can possibly have it as an option. So there is light on the horrizon for us to use SPL parts on a non-SSM car. So with the list of manufactures he gave me to look into i am now on a mission to get said bushings in poly and legally use them in my SPL arms and not be called a cheater. lol I will report back on my findings all i need is a 5/8 thread helm joint in poly or rubber. The SPC probably will work but i dont trust SPC.

Replace all of the sphericals with delrin/urethane. Go.

For the record, the cheater comment was meant as a joke.

Can't help but notice the last couple of pages have nothing to do with STR (or the OP's build)...might be best if mod moves them to their own thread.

True that, but from the sounds of it, it might turn into "SCCA ASP or SSM 370z Progress Thread.... It will be done!" and then this one can be closed.

Hahah!

I had a good time today. Drove a friends MX5 that is very mildly prepped for STR. It was so easy to drive compared to my car... Driving my 370z on 255 tires is like controlling chaos. The MX5 can carry so much more speed. Very frustrating to say the least.

I'm going to work on softening my spring rates this week.
I'll more than likely continue this futile effort to build a competitive STR 370z.

[Sh0velMan]

The 370 is much harder to drive on the AX course than people think, though it isn't as obvious until they drive something like an MX5 or a well sorted FWD car (civic, crx etc).

[chknhawk]

I got to drive my friends RSX turbo mild prepped and it was an experience to say the lease. Handling was a tad bit better but then I got in my Z and crushed my times just because more torque or something. I run ASP and have mild mods... still trying to sort out my suspension as well. So if I read everything correctly I need to completely remove the rear sway bar??? Is that just for AX driving/Track or can I just leave it out forever. I have stance coils in place now and stock everything else.. have some SPC rear arms that I need to put in and I might replace the stance springs with eibach or something else. SO... Rear sway delete?

Having some real rubber under these Z's makes a work of difference in my opinion. I'd like to see the results of what would happen if you ran the STR class, then during the same autocross put on some big sexy tires, and ran it for time only. Your thoughts on the difference would be enlighting at the very least I think.

[chknhawk]

Ive got r888 295 and 265s under mine. It carries great speed through and corners a lot better.... my big question is.... remove the rear sway bar??? Is this safe? Also ok for DD? Thanks.
