Hi there recently got to go through the ordeal of replacing the sump on my super spec

The car is now running healthy again and has a better sump guard

However it still scrapes on a lot of the roads around my area

If I can raise the ride height even a cm I think it'll stop it but for the life of me I cannot figure out how to

Attached is a pic of my coilovers I think I should be able to raise the ride height from here but I can't figure out how online it says there should be two rings bellow the spring I only have one there also is a hole for a grub screw but there is no screw in there

Any suggestions on raising the ride height?

Yes with normal coilovers there should be 2 rings, which when pulled together lock them, they were probably never intended for the use they are now being put to so maybe somebody has modified then with the grub screw. To higher the front end all you should have to do is wind the colar up with a C spanner. If there is no thread left then an alternative method would be to get a spacer to put between the spring & collar.

Thank you

Over the years I have had Gaz coil-overs with 2 locking rings and also ones with 1 ring + grub screw. The originals on my 2B had grub screws but replacements (from GBS) had 2 rings. I would recommend you fit grub screws into yours if they're missing so that they don't self adjust.

I would also recommend that you check your corner weights. I wouldn't rely on measurements alone to get your car balanced correctly, RH chassis were never that precise on dimensions but are easily set up by checking corner weights.

That made me chuckle
