Need help! I just bought a 04 roadster and when I take a corner at a decent speed the traction control kicks in.
The guy I bought it from had 245/45/17 on the front and 225/50/17 in the rear. After doing some research on this forum I found out it was because the different tire sizes causing the traction control to come on during cornering.
To try and solve this problem I put a set of 245/45/17 in the rear to match the fronts and stop the TC from engaging when cornering.
I took the car out for a drive after the new tires were installed and the TC in still coming on when I take a corner with any bit of speed! Why? Can anyone give me some advice on how to fix this? Thanks

 

Do you have VDC?

 

I don't know?, I do have the button to turn off the traction control. where do I check to see if I have VDC? My roadster is the grand touring model if that helps?

 

VDC and TCS are the same button. If is says TCS you do NOT have VDC.

The 4-square set-up should NOT be a problem with TCS. I assume you are running:

F-17x7.5
R-17x8

Inspect the wheels with a tape. Make sure you are running the same size wheels on the rear axle.

 

Grand touring will have VDC, no go read the top 100 question. It will tell you what is wrong with your car.
