How to improve straight-line rear traction on Rêve D RDX with TK?

Asked November 8, 2026

The racer asked

My car seems to have plenty of side bite but straight line bite isn't really there. What do I do. I am running a TK setup on the back

If by “TK” you mean the RDX’s rear toe block, try a small increase in rear toe-in and test again. It may make the rear feel more planted when you apply throttle, but too much can make the car scrub speed and resist rotating.

On the RDX, the rear RF block changes both toe and track width, and the setup data includes a “#7 TK” choice for low/low-grip concrete. That does not establish it as a forward-traction fix, though, so change only one thing and compare.

Since you already have enough side bite, I would not start by adding more rear lateral grip. Also check that the rear tires are clean and suited to your surface. If the rear toe is already high, look elsewhere rather than adding more.

What surface are you driving on, and what do you mean by “TK setup”: a #7 TK rear block, or a different setup?
