Looks like I may be taking a shortcut on getting my "new" but very tired 78 on the road when I get it back here (BTW - a PUBLIC thanks to both Stan SHaw and David Lloyd for thier gracious and unerring help in trying to get this car back to San Diego from CT - Thanks guys).


The situation that the car is in mechanically will need immediate shocks so that I can at least drive the car. That means I will probably put my bilstein/eibach/front-onthe-rear kit onto this car and buy something else for my 89S4 "CS/RS/SC" project.

Koni coilovers with hypercoil (linear) or Bilsteins with eibach (Progressive)?

Koni with eibachs?

I will be using drop links, poly bushings in upper and lower Front A arms and some poly in the rear sway bar mounts (see other thread)


Any BTDT? I can handle a hard riding car. There will be 18" hollow spoke Turbo twists as well.

Thanks

I have Bilstein and Eibach. They ride well on smooth surfaces but turn nasty on bumpy roads, too bouncy - not enough rebound control. If I buy Bilstein again I would have them revalved 15-20% stiffer on rebound especially on the rear.

I have Koni Sport on my other cars and they work much better than the Bilstein on my 928.

I too have 18" wheels on my 928 and the ride is firmer on sharp bumps but otherwise no change from 16". Actually my 18" rides smoother than my 16", different tires probably account for the differences.

I went the Eibach/Koni (internally adjustable rebound) route. When I first installed them I set the Konis to full soft. The rear felt really bouncy after a heavy compression. It felt like it wanted to jump off the ground. I then disassembled the coilovers and stiffened up the rebound to 80% max on front and 60% max on the rears. I like it a whole lot better on street and track. Car (especially the rear end) stays planted. If you want ride height adjustability with the Konis you will need to buy the threaded sleeves and adjustment nuts. I bought used ones for all 4 corners. Good Luck!

Koni/hypercoils think race car. Externally adjustables are highly prefered (and costly)

Bilsteins/Eibachs think Autocross, semi firm street.

With a lightened car such as yours (will be some day - ) plan on a modified spring rate like you mentioned, front springs to rear...

What is your intended use for the 89? That, to me, is the deciding factor.

Check w/ Mark from Pensicola (slow traffic move right windshield banner), I sold him a set of internally adj Koni's/old skool Eibachs fornt and rear. I heard he my not need 'em.
