Civic and tegs are BASED on the same chassis. The tg is lengthened a bit, but still the same platform. As for the teg shocks, they're valved a bit higher, so reason says that they have to hold a up a bit longer on a lighter car.... Mine don't squeak, don't rattle, ride great, and corner like a dream. I keep forgetting to mention, this is on an S model chassis. What's the difference from the Si? No sway bars! I'm doing those soon!
