EVERY single person I know (in person, not just on the board) who had the Pedders coil overs had strut failures. Normally this happens on the rear.
One member here had his fail 3 times (no racing and low miles). Eventually, we replaced his set up with the Koni conversion (don't recall what springs he used) but his coil over went in the trash!
The frustration that came with having to make repairs and wait for parts was not worth it. The stance was cool but the ride was harsh and very jarring at times.
I know you are not talking about coil overs here but with the number of failures I have seen I would stay away. It's just my personal oppinion. I'm not saying things cant go wrong with other brands as well, in fact I have had a Koni fail also but it not as common.
Strange thing is no one ever seems to post about the issues, sort of like people rarely seem to write about all the negative experiences they have had with Maryland speed. Talk to them though and you get an ear full. I don't understand it, guess it's just not worth the hassle.
Oh, and I don't think Mike White is with them anymore but you should stay away from that guy. He dropped my car off jack stands (didn't even tell me until I questioned him about the dammage) and curbed a brand new rim. The only thing good that came about going with Pedders is that it forced me to start doing all my own wrenching.
