Reptagon Posted March 10, 2021 Share Posted March 10, 2021 Im thinking of making a 4efe NA track car for the toyota sprint cup (E street class) but the thing I was wondering if the added chassis regidety was worth the added weight to the ep91 chassis over the ep81 chassis also could i buy a cheap 91 and cut some of the additional safety parts out to get the weight down?

daniel_g Posted March 10, 2021 Share Posted March 10, 2021 Ive had 2 GT shells that I ran around in n/a form. You can get braces cheap enough to stiffen them up. Never noticed a 91 being any stiffer to be honest. Quote Link to post Share on other sites
