SCCA STR 370z Progress Thread.... It can be done!

[Masterbeatty]

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.

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

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

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.

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.

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).

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?

[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.

The only purpose a sway bar on a car that it used strictly for track is for fine tuning.
If you spring rates are set up correctly you should not even need a sway bar.
But no track is the same and conditions change as the day goes on.
I have seen many a cars disconnect the rear sway bar because the car felt better and went faster on a particular track and day.
The manufacture puts sway bars to improve handling with out sacrificing ride.

You are not going to find a stiff enough spring to handle a stock 370 in the front

What?

[cossie1600]

Go order a 25k 30k springs, you can do it if that's what you want to drive on

[03threefiftyz]

25K spring is about right up front with no bar....I see no issue with it assuming you have good shocks that are valved for it. I run 1000-1200lb front springs with a bar on my car now...
