Coil over height adjustment question
Hi guys, as you can see in the pic below I have a bit of a ride height issue (red line) after replacing most of the front end panels with fiberglass bits. The old girl has Bilstein coil overs fitted and I was wondering if it is ok to adjust the ride height with the adjusting "lock nuts" on the bottom of the coil over assembly or do I need shorter springs?

That's what they are made for, adjusting. The only thing you have to check when lowering:
Is there still enough tension on the springs when lifting car (or jumping :-) ) /negative range. Otherwise spring can move out of seat. If not, there are two ways: -adding helper springs to avoid loose main springs or -cutting the rod (downside where fixing pin is). How much depending on the +/- travel needed. further info if you need. PS I just saw you have helper springs. Usually they are at the bottom, not top due the risk of moving sideways while shaking and therefore stuck at the top of the strut housing...

Yup! Drop that pup with the collar. Also, those wheels look pretty sick!

After adjusting ride height you should align/corner balance.

Not sure you have a big ride height issue, the read fenders are closer to the wheel than the front.
Set a rake of 1 -1.5 degree measured on the door sills.

Thanks for the assistance guys, first I will see what the rake is then take it from there. Will also see about swapping the helper springs to the bottom.

Swap the helper springs and then break the collars from each other. You might need to spray them if they have not been adjusted a while. Lower collar is to lock upper collar is to adjust ride height. Make your adj. making sure how many turns you did counted. Set the height to your liking and take it for a spin for 5 min. They will settle. Repeat as needed. Beauty of coilovers.
