  1. just heads up guys. The porsche design store at south coast plaza in orange county ca is showing the Porsche Design GT3 RS this Saturday March 5 from 2pm-6pm in front of their store at south coast plaza in Orange County. they're also serving drinks, food, and raffle of product. It would be nice to see their GT3 RS in person. I've always been a fan of porsche design special edition cars. The store is on the first floor on the macy's side of the mall. the store number is 714 662-2992 cheers
  2. For Sale - These are part off of my 2005 997. I have additional pictures. decklid and spoiler - $850 (new is $1700) front bumper - $95 (new is $450) stock air box - $195 (new is $550) stock mufflers - $250 (new is $950)
  3. one word, tread pattern! (or is that two) :thumbup: I put Bridgstone Potenza PE050 245/35/19 up front to match same model in rear with the SAME tread pattern and day and night difference - no understeer, handles like a Porsche again. the 245's up front match the 305 rears in almost the same ratio as stock 235/295 combo on the 19's. calculate those tire circumfrances, offsets to match what those Stuggart engineers formulated from the factory (using online tire size calculators), but don't forget about matching tire tread pattern front and rear. Different model tires can make a world of difference. :drive: Thanks to Carlos at Wheel Dynamics in CA. He's the owner and has lots of Porsche knowledge - not to mention a nice guy to do business with. I would highly suggest them if you're looking for wheels/tires. www.wheeldynamics.com Also came across some helpful understeer oversteer correction tips - one being tire pressure (raising front tire pressure and lowering rear pressure by about 5 psi will noticably reduce understeer. common tips here - http://www.nyracer.com/overunder.htm
  4. forum members DVell and Loren had some great insight into this. Dvell mentioned that the GT3's suspension geometry is setup for the 305/30/19 rear while the carrera 2 is setup for 295/30/19 in the rear -even though they seem like the same car structurally. This, and the fact that there is more tire in the rear while the front stays the same causes the understeer. They both suggested going back to stock 235 front and 295 rears. Altough 245 up front will help neutralize the understeer somewhat. Thanks for the insight.
  5. thanks for the feedback. I am going to go with 245/35/19's in the front as it seems to be a better match to the 305/30/19 rears based on online tire/wheel diameter calculators. I am hoping this will offset the sever understeer I am experiencing. will let you know findings.
  6. I just experienced this first hand. went with fatter tires in the rear and experienced noticable understeer. I have a 2005 997 carrera 2. I upgraded my 18" 997 carrera III wheels (235/40/18 front and 265/35/18 rear) to new 19" Sport Design wheels with 235/35/19 front and 305/30/19 rear. the 305 rears is what Porsche puts on the 997 GT3 so I figured it would be okay instead of the 295/35/19 on the Carrera S (although they go with 19x12 wheels - does wheel width make a difference as long as offset is okay?). I went with Bridgstone Poetnza E050 tires in the rear which are porsche approved and because the tire center was out of matching Bridgstons for the front I went with Toyto Proxy T1's in the front. now I am experiencing massive understeer. The Carrera S 19" come with 295/30/19 instead on a 19x11 wheel, is this my problem? Since my new rears are 19x11 do they need to be 295 instead of 305's in the rear. Some people have suggested adding some width to the front tire will reduce the massive understeer - changing the front from 235/35/19 to 245/35/19 but Porsche does not provide an N designation for this front tire size. N0, N1 etc are porsche's stamp of approval on tire size, tread pattern etc for each brand of tire. Can anyone help. Should I go wider in the front, or cut back in the rears or will getting bridgstone fronts to match the rears fix the understeer? PS - I had no idea tire/wheel size made such a difference in handling. Here are some before and after pictures -
  7. Thanks Loren, even the porsche dealer didn't know about the issues with the earlier model hoses. Great Porsche Knowledge!
  8. Is anyone using any secret weapons against cabin noises? I've heard of a foam that you spary in the area the noise is coming from. cabin noises are pretty common in cars with tight suspensions but man, sometimes it sounds like the car is coming apart. any DIY would be greatly appreciated
  9. just purchased a 2001 996 TT. Second week I had it I upgraded the ECU with REVO's 5 hour free test drive. before the ECU upgrade I was getting 0.7 BAR max, after the upgrade I got 0.9 BAR max. I was told there is something wrong I should be getting 1.1 BAR and was told to come back another day to check things out. on the way home, I accelerated under heavy boost then....heard a POP and PASM failure light, ABS failure light came on, lost power and the engine started choking. I limped home. found that under heavy boost the left intercooler hose had popped off. This suggests it may have had a leak which was preventing me from reaching the 1.1 BAR. I know with heavy mods the hoses must be upgraded to silicone hoses, but with just an ECU upgrade the hoses should have handled the boost. Does anyone know if 2001 hoses were replaced with improved hoses with more secure connectors? Are these known to fail or leak?
