So after being on the road for ten years I am in the process of doing some suspension upgrades. One change is to add a little more ride height. Went to adjust the front coilovers, and they are both missing the grub screws! Guess I should use a little loctite this time :-) Does anyone know the size of the Koni coilover grub screw offhand? I don't want to take a shock to Ace hardware to figure this out. Thanks so much

Leave them out

Strictly answering the question, I believe they are 1/4-20 screws. You can get them with nylon tips to prevent marring the threads of the spring adjusters; here is an example:

I have no dog in the screw/no screw debate ;)

Thanks Chopper - I will probably replace them (with some blue loctite)

As rich grsc said "leave them out". I have over 4,600 miles on the car with no ring lock screws and they have not moved at all. I have them marked and check my ride height usually annually.

I agree the best place for them is in the trash.
