Hi all. My new 03 C4S starts to drift to the right in about 2 seconds without steering correction on long straight 'flat' divided Hwys- worse on the far right lane than on the far left lane. It' been like that since day one. Dealer checked and confirmed a slight pull to the right but claimed that it's due to road crown, so it's NORMAL, and I am not buying it, because I cannot duplicate the same behavior on the same road with the other cars that I have. Is this normal for a 996C4S?

 

No. Try another dealer.
Could be tire/wheel or alignment... they should solve the problem.

 

I agree, total BS from the Dealer! Try another dealer or call PNA and let them know.

 

I live in South Florida where most of the roads are crowned to the right to make the daily afternoon rains run off the road. I bought a new 03 C4S and when I left the dealer I had a slight pull to the right. I thought it might be the road (I-95) when I got off the road near my house the car still had a slight pulling. I had it checked the next day at the dealer and they said the settings were correct. I took the car to Bobby at Foreign Affairs my local independent Porsche shop. They put the car on there alignment machine and showed me the settings were correct, he recommended that I try an other set of factory tires and wheels he had in the shop. Guess what no pulling, he said he has seen several new Pirelli tires that pulled because of a tire/belt problem, he put my tires/rims back on. The following week I had Porsche change the tires and there were no more problems.

 

I have been up & down Hwy 1 from VanCouver BC to San Diego, what a BLAST! I'll do whatever necessary to restore my baby to a 10!
Thankyou bobC4S for sharing your experience, Loren and Silver Bullet your help and support!
Love this P-community.

 

was it windy?

 

I have changed a few time ago the 4 wheels and experience a vibration and nervous the car. Every time the supplier balance the whells and I drove several kilometers (1000) they need to be balanced again. After the Pirelli responsible saw the problemm they decide to change the 2 back-wheels PZero Assimetrico 265/35-18 whitout cost and the problem was away.
The wheels have a lot of steps and handwork to produce them and there could be potencialy problems cause it is composed from many components. Each serial of the same wheels is different.
