    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 make Rear STB's for all first Gen W's except the Cutty verts.....

    The new Z06 exposes European sports cars for what they really are....overprice, underperforming snobs.

    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.

    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

    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?
