Thinking about Coilovers... supporting suspension components needed?

Hey guys,

I was contemplating coilovers for the car.

In the past when lowering vehicles I have always had issues with swaybar links & bushings wearing out much quicker.

I do know that I am not going for the slammed look but just a 1 inch drop MAXXX. The roards here in Ontario are definately not slammed-friendly.

My questions is for those already running coilovers, have you guys changed any suspension components since?

Cheers!

You definitely want rear shock mounts, I would also upgrade your control arm bushings as those tend to fail prematurely on stock suspension.

I put about 12,000 miles on my KW v1's on my old 330Ci. There were no issues with any linkage or shock mounts and car was driven fairly hard. The kit came with new front sway bar links and I upgraded to H&R sways front and back with no issues. I'd go with KW or Bilstein. They're good set ups and seems to be the favorites on here.

1 inch max drop? That's about the minimum drop some brands drop. Others drop more then 1"
You won't need endlinks for the rear, but RSM's are recommended.

I don't know of a coilover that won't drop more than 1". Why coilovers? H&R cup kit?

I'd have to recommend Bilstein Sports and springs for a modelst drop.

who wants a 1" drop at max? anyway bushings and endlinks go bad, you should be inspecting/replacing them regularly, rougher driving conditions=quicker wear of those things. coilovers might increase the wear, but big wheels take like half the life off of bushings.

Even if you don't do all these things right when you do your suspension, more than likely it will come soon as they usually need to be replaced around 75k miles or so.

2 Front Strut Mounts
2 Heavy Duty Rear Strut Mounts
2 Shock Mount Gaskets
2 Z3 Reinforcement Plates

You will want to get those parts to install the coilovers. then on top of that, it would be a very good time to do control arms/bushings and or rear trailing arm bushings.
