FYI-
BMR lateral bars work in the rear of the 95-99 Monte Carlos
Held Motorsports made STB's (front and rear). I do not know if they still sell them. The older rear bar had a poor design. They also make various other upgrades like coilovers, though Shane hated his that had their old design- too noisy. The new coilover design was supposed to cure the noise issues, but I haven't heard much about it.

I've looked at a few in J/Y's and i'm not sure how to do it.....

its prolly possible...but it might get funky.

Id imagine you would have to do it down low on the strut tower or put some big bends in it, both of which will make it not work near as well and not really worth it.

[3.1cutlass]

What site are these part numbers from?

[pwmin]

parts needed to make your own coilovers (appx. $150-200)
sleeves: http://www.a1racing.com/index.asp?Pa...OD&ProdID=1734
nuts: http://www.a1racing.com/index.asp?Pa...OD&ProdID=1744
any of these springs should work: http://store.summitracing.com/egnsea...115+4294787535
you can use the stock mounts and stock struts. you may have to modify the top of the strut body for the sleeve to fit over it

[DEI37]

Does any know about better control arms for the front of a Cutty? I know the '97+ GP's have better options, but what about us first gen cars? I NEED to get a set.

Aweb80...how much for a rear STB in a Cutty sedan?

[EL~GTP]

Can I take the first gen strut upermount to fit on 1.5gen coilover ?
I want take the 1.5gen suspension systeme to put on my GTP 1994, I have a lot of pieces crap on my firt gen .. and I want swap at coilover with a 1.5Gen, but I don't know when put the first strut upermount in 1.5gen strut coilover .. thanks !

[cutlass supreme FE3]

I want to put bigger swaybars but have FE3 already.
do they make bigger that 34mm for front and 14mm for the rear?

[99Luminut]

Just a note about Sway Bars for Luminas. The Addco Sway Bar part #639 listed for 95-99 Luminas will NOT fit the Lumina chassis. I know this because I ordered one of them from Addco, and when it arrived, it was not even close to the configuration of the bar on the car. I called Addco and told them about it and emailed them pics of the bar. They checked with their engineering department and said that I was right, the bar would not fit a Lumina chassis. They had assumed that all the W-bodies used the same chassis, and they don't. The Lumina is different from the Pontiac, Buick, and Olds chassis, and the sway bar design is completely different also. The only heavy-duty rear sway bar that will fit a 95-99 Lumina is the factory one from the Ride and Handling package used on the LTZ and Police suspensions, Chevy part # 10242079. Hope this saves somebody else from making the same mistake I did.

IIRC the Monte Carlo Z34 bar is the same. Should be a good find at a local yard.

[cutlass supreme FE3]

will it fit a 1988 first gen?

[ghrarhg]

cutlass supreme FE3, the addco bar 7/8" listed on the first page works for first gens like ours. Also, do you already purchase the 34mm front? FE3 in 88 only had a 30mm bar IIRC.
