The front 2 are easily accessible without the extensions, two for the rear will be required though, usually they get located on the top of the in boot strut brace for coupes or inside the roof tonneau for roadsters. Anybody who wants to actually adjust the rear coilovers will want them.
If I didn't already have these coilovers, I'd be on this like a rash, great price for an excellent upgrade.
Sweet. Yeah I'm up for a pair of extenders too then.
