I am in the market to buy some coilovers soon. What is the average lifespan of a coilover from street/track use before the shock/strut starts leaking? Being not able to rebuild them really makes a valid point when you're basing a buying decision. i.e. HKS, Apexi N1s

 

Not sure about the lifespan, but these are worth checking out..

I believe M2 may market a version of these for the 3rd gens.

 

i think that may depend on the individual dampers. The Penske Technical Manual sez to do the following every 30 hours of track time or annually: change oil, replace the shaft seal o-ring, wiper, shaft bearing o-ring, reservoir cap o-ring, piston o-ring, floating piston quad ring and valve shims.

Hmmmm....what did i get myself into?

 

Yes, M2 does sell these and I highly recommend them. I've had mine since last July. They were $2100 back then I think $2400 now but at least you know what you're getting vs. the Japanesse brand coil overs. For the money, the Apexi, HKS, etc. are too much of a gamble.
The M2/AD are easily rebuildable, you can buy a single corner if damaged, the Eibach ERS springs are readily available for changing spring rates, they come with upper pillow mounts. Do a search, there are a few people on the Forum running this set-up.

Not sure how often they require rebuilding or service but the manufacturer (Ground Control) can be contacted easily to find out.
