Its posted, with a TBA date that was supposed to be Sears Point (infinion) we will see. Now, thats a class for fair 928 racing. and by the way, the 928 will dominate if raced in this series. the rules are perfect for the S4. just find a set of 9s all the way around (ill use my second set of fronts for the rear with some spacers) run at 300+hp with 275s on all 4 corners and have some fun.

Mark,

Talk to Stan Shaw. He has had many exchanges with the guy running this series.
Looks like he will let us run PCA GT2 rules for the first year. After that we will have to go to little tires.
www.928racing.net is looking to run at a few of those races next year.

Ive been talking to him as well. had some good conversations. If you look at the rules, there is no reason to want any concessions. putting my 275s in the rear work fine, and with my power and weight, im ready to rock, and stan would be too.. GT2 rules??? doubt it GT2 calls for anything goes on a stock chassis and even slicks.

their rules are perfect for our cars to be competitive.

Remember back when Lotus was dominating the Escort series with the Esprit? If you dominate they will penalize you with weight to keep things more competative. Fair on one hand but unfair on the other. Seems they will always make a rule to keep things in their favor. Best of luck. Hope it works out. I enjoy reading about escapades.

GT2S setup w/ a 5L

mark kibort

based on times posted by these guys at VIR, and the types of cars racing, inclucing one of the guys i race against here in California. the GT2s 5 liter setup is fine, but those tires will have a little more advantage than is really needed. its a small field (or was last season) so its not going to be a big deal, but it may saddle the 928 with weight and then with the smaller tires, we will really be in trouble!! I know Stan has 2 sets of rims, he should just do what i will if they come out west. put the front 275s on the rear and use some big spacers to get the same effective width. that should be fine.
Be great to see how he does. which race will he be going too?

Not he, we.

Haven't decided, but Pocono, BeaveRun, and the Glen are races Stan and myself have done via PCA.

FYI-Stan doesn't have a second set of rims for 275's unless he got them over the past month or so. His second set is for 245 rain tires.

I've run 275's on my 11" rims, but they want us to run smaller wheels. Works, but don't like it. Will be a challenge at BeaveRun with the last turn before the front straight. I chewed up the 315's trying to get on the power early enough.

cetainly the 275s will be a little more skatey! but, they should "work" when you are forced to comply with their rules. heck, if Griggs can run 275s with all their power and more weight, i think we (you , stan and myself) should be ok for a sprint race. plus, then you can rotate the fronts to the rear for longer track wear. try Toyo RA1s. what can i say, as fast as hooseirs and they just dont wear out???? You know how often i travel to Laguna. less than .5 second difference between hoosiers and toyo RA1s. go to a speed GT race and grab some out of the garbage can (you may be forced to pay $100 for a used set of 4) try em. they are awesome and seem to last forever! (on our 300hp'ish cars)

Their schedule still doesn't show anything out West. BTW, most of the racers also run in NASA American Iron, and they aren't afraid of a little rubbin'.

I keep reading about you guys wanting/needing bigger tires and not much on fine tuning your suspensions.

Off the shelf street springs and shocks are fine for the person running DE's, but if your going to build a track car, you need more!

Learning to get the weight you have to work better for you is better than just patching the problem with more rubber.

When I used to race (tires size was spec’d out), I had at least 5-6 sets of springs, 10-15 different shocks and tires with different compounds on rims with different offsets so that weight transfer could be changed to suit the track and conditions.

If your sliding all over the track going in or coming out of the corners, look very hard to see if you getting the weight transfer you need to each corner to plant the tires you have correctly.

Your tires are just one of many variables that need to be looked at when setting your car up for each type of race or track.

For a good fundamental start, take a look at Tune to Win, by Carrol Smith!

It doesn't list a west coast race at all? If they come to Laguna or Sear point, I would definetely come out to watch the "marks" kick some live axle butt!

John Veninger

100% right! I have custom shocks, but they are not adjustable. Would love a set like Anderson has, but $5K+ is a bit much for my "club racer".
Adjustable sway bars and brake bias help a little.

John a coil-over is just a coil over. The mounting points are the only thing that is holding you guys back from getting into inexpensive solutions.

With a little imagination and the help from a machine shop, you guys should be able to come up with a better (cheaper) solution for front coil-over’s. The rear’s will be a piece of cake.

Once you come up with common race mounts for the 928, you will have more shock options to choose from without getting into the big dollars.

Once your mounts are made to fit common race shocks, you will be able to have guys like these custom made to your spec’s for a lot less. This also applies to springs as well.

Curtis,
Not holding me back
I have custom solid mounting points w/ Bilstein race coilovers and hypercoil springs

John your on top of the curve!

Can the Bilstein's be rebuilt or revalved?
