Suggestion

I have standard bump stops with my -30mm + drop and I also have fitted poly bushes to my ARBs and coffin arms, the way to find out your ARB size is use a Vernier caliper or if you don't have one use an adjustable spanner and measure the gap between the jaws.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Folks, with my suspension deteriorating I have been force to swap out the shocks and dampers. Have gone 30mm springs and Koni sport dampers. Last year I bought all new coffins arms, tuning forks and cross braces as well so will get them all replaced. Obviously whilst doing this it makes sense to replace other components at the same time so I have listed at the moment with some questions. Top mounts front and rear - where best to get these as Im on a tightish budget? Bump stops front and rear (do these need cut if lowering 30mm?) Anti roll bar bushes - stay standard or go polybushed? What size for M030? Anything else Ive missed out that folks would get in advance?

POST 3Original post

I got Sachs top mounts from Autodoc. They were identical to the ones I took off except the porsche part number had been ground off.

POST 4 / ORIGINAL POSTEROriginal post

Thanks have a set of verniers so will just check. Yeah I've seen the Sacha and Lemforder ones. Rear top mounts seem very expensive. Anything else worth replacing? Any of the arm bolts one use only?

POST 5Original post

You only need to do your front top mounts. Rears will be fine as they don't get the same hammer as the fronts.

POST 6Original post

Going -30mm you may have trouble acheiving sensible geometry with the rear suspension. You may well find that adjustable rear toe links are required. The cheap Chinese versions (Hardrace/Godspeed)are fine if you're on a budget but will be less corrosion resistant than more expensive versions.

POST 7 / ORIGINAL POSTEROriginal post

Ah yes forgot about that. I'll look into them. Thanks
