Spring question + track vid

First the question. I have a very basic suspension setup on the FD: Tokico Illuminas w/Eibach pro kit springs. I've found that under hard braking and cornering on the track (especially with a passenger), I'm getting some front tire rub with the fender liners on both sides. Tires up front are 245/45/17s. Are the springs too low (1" drop or thereabouts) or the tires too big? Should I shim the spring or perhaps the top-hat mount in the shock tower to gain additional clearance or just replace the springs outright? Larger bumpstops? I don't really want to lose suspension travel. Any recommendations?

Rears are fine at 275/40/17 and there appears to be more fender gap in the back than in the front with this setup.

Second, here's video from the other day where I was having the problem. The problem is most severe in the carrousel due to the increased grip of the cement and banking.

Thanks!

You need stiffer springs.
