I'm replacing my lca's and panhard bar today with slp take off ones (got them at a great price, so not bothering to upgrade to BMR yet Thanks Louis!). My question is what bolts does everyone use when replacing them? Mine are in pretty bad shape but it looks like at least on the panhard bar that they are a form of metric double shoulder bolt (two diameters on the unthreaded portion). I can feel two dimples on one side of the bolt holes in the new panhard bar which would ride on the smaller diameter shoulder. Can I just replace with a regular, same grade metric bolt?
Any thoughts are appreciated!!!

 

I would guess you could use your stock bolts if they're in good shape. Yours aren't, so I'm not too sure really. I'm going to be replacing my panhard bar and LCAs very soon, I'd also like to know.

Anyone?

 

I did the swap, ended up using the stock bolts for the panhard bar with new flanged stover locknuts. Purchased new M12 bolts and locknuts for the lower control arms though. Worked out fine.
