Need some opinions to make a good street suspension
Chris - If you're looking for tubular Upper Control Arms, go to http://www.reillymotorsports.com/store/product.php?productid=16164&cat=265&page=1.
All of the RMS parts are top-notch quality and strength. Our club built a '68 Valiant last year as our charity raffle car and used the complete AlterKtion front and Street Lynx rear suspensions from RMS. That car handled like a slot car even with the 400" big block weight on the front end.
IMO you won't find better quality suspension parts.
Do yourself, and your family, a favor and save up for the best parts so you only do the change once rather than replacing inferior parts later.
