dear god... With the prices that i am seeing, i should go ahead and save money to bag it. Wanting over $1000 for coilovers when u can get 95 and up from 150-299.
Why couldn't 3 gen coil over be made to fit? Even if you had to put 3 gen spindles in, it would be less than what they want for 2 gen coil overs.
Even though designs of the front may be vaguely similar, they are quite different, I looked at going this route.
The front strut on a 3rd gen is smaller in diameter, which makes finding sleeves quite easy. The steering is connected to the spindle in the 3rd gen where as on teh 2nd gen it is connected to the strut, so to use 3rd gen struts, you would need to use 3rd gen spindles, but then you would also need to use the 3rd gen steering rack, which will require a redesign of the steering linkage. The front sway bar would need to be relocated possibly swapped with a 3rd gen sway bar. The exhaust would have to be redesigned (on a V6) 2nd gen, since the steering rack would go in the approximate area where the sway bar previously resided. To do all of the above mentioned, would cost more than $1000, in parts alone, let alone actually getting it all to fit.
The rear would require a redesign of the upper shock mounts to be able to support the weight of the car and bolt the upper strut mounts to, 3rd gens use struts in the rear, probably some re-enforcing or modification to the axle to accept the lower strut mounting design.
So in order to use the $300 3rd gen "coil overs" you would spend probably as much as buying a (used) 3rd gen.
Besides those "coil overs" you see for $300 are not actually Coil overs, but a sleeve and a perch, with a spring between them. Coil overs were never designed to adjust ride hight, but adjust corner weights. Hight adjustment is made via movable mounts, the perches at the bottom of the spring are for minute changes. You also have to think about the stroke of the damper, static ride hight should have the damper at a neutral position, in the middle of the throw or just a little toward the top half of the stroke), not something you are going to be able to do by using sleeves alone.
