SCCA Solo C Street Discussion

[G_Ride]

I have a question that hopefully someone here can help me with. My region had their second event yesterday and there was a Porsche 968 that was outright decimating CS. He said he had a 968 clubsport, which never came here, but he could just have the M030 suspension packge and doesn't know better. He's never ran with SCCA. From what I found the M030 package comes with adjustable height suspension, at least the front struts are height adjustable. The rear shocks on this guy's car were height adjustable (KW's from what I could tell and with stock looking springs), but does anyone know if the rear shocks were height adjustable on the M030 package?

From: http://944turbo.net/?p=277

Included upgraded 30mm front and 25.5mm rear sway bars,
upgraded front inner, outer, and drop link bushings,
improved front castor mounts.
Thicker front anti-roll bar
25.5mm rear torsion bar (a standard 968 option)
Koni shocks, which were height adjustable, and included an adjustment tool.

So if he has KW's that's fine... the m030 package had height adjustable koni's. I wish I had that option on my old '84 944 turbo... was '88 and later.

Even if his car didn't ship with that option and the option was available for that year of the car he could swap in all those parts. The hitch is he'd have to swap in all of it (although he would have one sway bar free to change).

I appreciate that. What has me confused though is what another competitor in CS found was this http://www.weissach.net/968_M030-Opt...ocksAndSprings. Based on that, the front struts are height adjustable, but the rears are not?

The adjustable ride height isn't particularly the issue... anyone can use adjustable ride height dampers, as long as the spring seat is dimensionally the same as the OE and it is set to factory ride height with OE legal springs.

See this post though from quite a while ago:

Thanks for all of the clarication. It threw all of us off since I don't think anyone in CS has seen a 968 or one with the M030 package before, and I have basically have zero knowlegde about Porsches. I wasn't paying attention when he was running, but everyone was telling me the 968 was extremely flat in turns. When I actually took a good look at the car, the -3 degrees of front camber and practically having no fender gap (on 18's with the +/- wheel diameter rule and using the height adjustability), it caught my attention.

Oh well, I guess I'll just need to get faster. A lot faster....

To add to my previous statement... it IS a problem if the package did not include ride height adjustable rears and he has the KWs with the ride height not at the OE setting. That is illegal.

I've been told that the rear height is adjusted on those cars by the rear torsion bars. I'm assuming the adjustable collar on the rear is for the spring, which very much like a factory spring. I'll have to talk to the 968 driver next event.

I have been looking into the 964 as I don't see where/how in the rules the turbo model is excluded from CS. Did I miss something?


Also wondering if the factory wide body non-turbo 964 is eligible for CS? I haven't been able to look into it too far but from the looks of it, 18x8.5 front wheels and 18x10.5 rear wheels. That kind of rubber and AWD would be ridiculous.

964 is not listed in appendix A from what I can find, which means it is not eligible for CS.

Page 168 right below the 968 listing.

Ahh tricked me by adding a name in front of the number haha.

The Porsche 968 with the M030 package gets 17x7.5 fronts and 17x9 rears. They can fit a decent amount of tire underneath. The 968 owner told me can also get up to -3 degrees of front camber on those cars, too.

Here's why I'd think no on turbo 964...

CStreet lists "Carrera 2 and Carrerra 4 (964 Chassis)"

That only means Carrera's that are 964's, not specifying all 964's. The little bits I've seen only refer to it as "Turbo", not "Carrera Turbo".

There is proof within other categories (no be all end all) that the 964 Turbo is actually called a "911 Turbo (964 chassis)" for the ASP listing.

As to Street, C specifies "911 (non-turbo, NOC)", but oddly there is no 911 NOC anywhere. There's tons of specified 911's, but no other category to catch a 911 964 turbo anywhere. It's an uncaptured car, (and also not currently eligible for National competition).

I have doubts it would be classes in C if asked.
