Thanks again guys, but after reading the posts about overall width, I guess I'll stick with the 26mm tires. Right now, my car is 200mm rear, 199mm front with Yok 26mm foams. Granted, I could adjust the pillow balls to compensate some for wider tires, but not enough to keep the car legal. And I'm not putting out the $$ for the Kawahara conversion. There's a couple of tracks I run at that pay CLOSE attention to car widths. I'd like to keep my car legal (even on tracks that don't tech) so that I don't have to keep changing things every time I go to a different track.
The funny thing is, they are ANAL about some specs, but no one has ever pulled apart my engine to see if it was legal. I put a stock cooling head on my RTU and everyone assumes it's a stock engine. I'm thinking about running my "Richey" head at those tracks this year, to see if anyone wants to tear down the engine. But if they wouldn't let me run, it would probably start a war.
And, yes Dennis, I know it's technically legal, but we both know how some guys are about your engines.
