Don't know, I've installed bunches of IFS over the years, Heidt's Kugel, Weimer's, TCI, Speedway, and even a company that's a subsidiary of Shell Valley..... all are DOM tubing, poly ends, tig welds, forged spindles, etc.various brands of coilovers.... Granted Heidt's and Kugel have the name, but when quality is the same, no reason to spend a bunch more.....

As for customer service, there's a bunch of companies who have equal or better customer service then Heidt's..... Ever tried to order something out of the normal package with Heidt's????

Jim also said he was building a driver, not a show car.....I'm the first to say that quality parts are worth more, but I don't see paying extra $$$$$ just to have the "right" decal stuck on a cabinet in the shop.......
