I have a 1987 trans am WS6 parts car, motor/tranny gone but was a 305 tpi...

HAs the big sway bars, and what not...

I have my 1990 RS that really badly needs its upgrade... So what do i pull exactly?

Sway bars, of coarse...
Springs, they sag but are much firmer...


What else?
I've heard the WS6 or whatever had a quick ratio steering box, true or not?
what can i pull off for maximum gain, without spending an extra penny, i already have a set or KYB GR2 shocks and struts waiting to be installed...

 

The brace that bolts where the front sway bar is. Dont forget that.

 

I dont think a WS6 Firebird comes stock with the wonder brace under the front sway bar. I believe that Iroc's are the only ones that come equipped with the brace from the factory.

 

how much of a difference is there between IROC suspension and WS6. and what are the differences? i've been wondering this for awhile now.

 

me as well... i was under the assumption WS6 suspension was a better upgrade then IROC...

 

it is. the spring rate is firmer, and the sway bars are the same sizes, but sometimes bigger on the WS6. The steering gear on the WS6 is quicker, too, only 2-1/2 turns lock to lock. I'd grab the box, the bars, and the springs, and I'd see if the rear end is better than what you have. if so, keep it at least for a spare, if not for replacement.

the thing is, they never put the IROC wonderbar on the WS6. but for $45 from Lon at TDS, you too can have one.

 

ok so springs, sway bars, gear box... rear end sucked so no...

the new rear sucks for drum brakes... but i'll deal, the old 9 bolt was a POS....

 

so i guess i don't understand. do you like the rear in the donor, or no? so far your list is good.

 

I also, found a ws6 car, and would like to know more about the steering box, how would swapping that on my 89 RS affect driving????? Thanks, Tom
