I have a 2008 Acura TL type S. I'm looking to improve on the handling of the car. What suspension would you choose if you had a choice of Tein Street Flex or the XLR8 ISC coilovers? Also don't mention HT Specs coilover kit... nothing against Heeltoe auto but i purchased a set for my TSX (type II version 2) after all the good reviews that were found on both popular Acura forums only to find out that they weren't suitable for the New England roads. I've replaced over 6 dampers in a year's period before giving up on them. I'll blame it on all the uneven roads and potholes in New England since all the people in the West Coast and South don't have issue with them.

 

I've heard great things about both, but it depends what you're looking for. Teins typically provide the smoothest ride but the ISC coils will go lower.
