Thanks Neil and Seaball.
I got so much traction, that I easily make traction roll. And yes, I've already reduced droop, stiffend up the suspension etc.
Problem is, we have some bumps in our track, so I'm already on the edge about having stiffer suspension.
These tires are approx. 1/3 of the normal price for 4 tires/inserts/rims. So it's worth a try. Besides, they come pre-glued, and I hate gluing tires
But if it wont work, I'll guess the next step will be harder inserts.
Funny thing is, I'm always running harder suspension and inserts, than most other guys at the track. Recently, we had a race. One of the mates was wondering I could drive as fast, as I did, with such a hard setup. But it works for me that way.
So what the heck...
