Continental DWS tires, love'm. I run 36 psi rear and 38 in the front and the car handles beautifully and still maintain "most" of the Lexus luxury ride.
Nice..

question..

Hows the balance in braking front Vs rear? i assume the rears are using a smaller sized piston correct?

Im asking cause i have willwoods 4 piston all around, my rears use smaller pistons but im wondering if its too much bite for the rear. I recently locked them up @60mph and the car wanted to go sideways, kinda like if you were to pull the e brake on a 240.. So im trying to see if my rears are the culprit.

Im getting a set of those tires soon. How is the wet traction and handling?

thanks

I'll have to take a look tomorrow but from memory the rears look smaller than the fronts so I'm presuming the piston size must be different. I believe you are correct.

Given the circumstance you're describing you might check into a brake line leak of have the whole system checked for air bubbles.

Thanks for the compliments fellas! This is my daily driver, I leave the crazy stuff for my weekend car, so I really can't go lower but 0 wheel gap in the back and 1 finger front.

thanks..Nothing wrong with my brakes, actually they work too good, and im thinking the rears may be overpowered causing tail spin at full lock..either way..thanks..and NICE CAR

Thanks Man! Wildwoods are at the top of the class for BBK's, I'm sure it's an overpowering issue or something simple. I did NOT do my install because of the brake line replacements so I'm not an expert on the subject.
