My car idles around 850 so that shouldn't be a problem if its tuned right. The wife would probably have my head if I added another track day this year unfortunately, lol. FYI I managed to get 275 and 335 hoosiers to fit yesterday (3.5 fr and 3.0r) camber and they absolutely rocked yesterday at mid ohio so you should be able to get them to fit as well. The left rear did tend to roll over a bit despite 36 hot pressure though. Getting some stiffer springs from Steve Weiner should hopefully help that.

Now the big question, are they worth the extra $$ in performance over the 245's? My other question would be if your braking points were the same with new setup. You added a half deg of cambe which one would think would extend them but you also added more rubber up there
You should tell your wife that she can go shopping in South Haven while you go play at the race track. That way you are both happy! We have a few guys doing that already for this event

No question the 275's are better. Much less understeer. Didn't get hard on the brakes as the current ones are quite worn. Will test next month at Elkhart after 380mm ones from Steve Weiner are put on next week. South Haven won't fly but I'll run proffer Saugatuck and see what happens.

I've been thinking of them lately. The cargraphics can accomidate them just fine so I guess that means I HAVE to buy them right? haha. 4 pot or 6 pot? Lats time I checked the track pad selection for the 6 pots were limited to say the least (assuming these are the off the shelf brembo units)Hope you can make it to the event. Would love to pick your brain about a few things prior to driving my motor down to todd later this fall.

993 Cup Cams
Does anyone know how 993 Cup Cams differ from the RS cams and so whether they would be a good alternative for our cars.
The part numbers appear to be:
993.105.246.70 (rhs)
993.105.247.70 (lhs

Does anyone have any info on the RS Tuning sport cams they offer for the 520ps kit http://www.cargraphic.co.uk/index.ph...,1052/&start=3 , how do they differ from the 993RS cams?
