GP4U2NV Posted April 9, 2009 Report Share Posted April 9, 2009 I would like you guys input on the modifications I am doing to my 1993 Grand Prix SE. Also I would like other improvements that I should do to the suspension and brakes. The vehicle is a L67 swapped vehicle. List of things I am doing: - Monte Rear bar with new ES end mounts (OEM hangers) - 2nd Gen Rear Spindle and Lateral bars with ES bushings - 2nd Gen GMPP trailing arms - New KYB Grb-2 Front and rear struts. - Coil over set up that has been discussed - Rear progressive rate springs 174-300 (iirc) (deleting mono leaf) Modifications to vehicle brakes / suspension already: - Monte “intrax†front lowering springs - ES front bushings on the sway bar - Front R.A.T. Strut Bar - PowerStop Drilled front and rear rotors - PowerStop Front and rear brake pads - Goodrich SS brake lines (front current – rears will be done w/ rear suspension) What I am after: - I would like to see some improved braking. - I will not be auto-crossing the vehicle but an improved handling while still not being harsh is what I am after. - I would also like to (after I get the rear higher) to shove the rear wheels out. <Your advise???> Quote Link to comment Share on other sites More sharing options...
Andrew Posted April 10, 2009 Report Share Posted April 10, 2009 - You really need a RSTB. Those help a ton with handling on FWD's. - Your braking components really seem top notch for stock style. I know they probably still arent spectacular, thats just the curse of W brakes. There are upgrades out there for you though.(13" front kit, 1.5 gen oem rear upgrade) - To push the rear wheels out, either get new wheels with a smaller offset, or get spacers and some longer wheel studs.

GOT2B GM Posted April 10, 2009 Report Share Posted April 10, 2009 He's using the 2nd gen lateral links which are longer. They'll push the rear wheels out a bit. I would advise to get bolt on spacers over putting longer wheel studs on with slip on spacers. I put 1" thick bolt on spacers on the back of my TGP to give it a nice wide stance.

I held the 2nd gen rear lats up and they dont look longer.......maybe a 1/4 inch Where and how much where your spacers? Quote Link to comment Share on other sites More sharing options...
jtwmechanic Posted April 10, 2009 Report Share Posted April 10, 2009 would using off set wheels do the same thing? Quote Link to comment Share on other sites More sharing options...

GOT2B GM Posted April 11, 2009 Report Share Posted April 11, 2009 I bought the aluminum bolt on spacers from a local supplier although you can get them on ebay about $100 CDN for a pair. 5x115mm 1" thick 12mm studs Quote Link to comment Share on other sites More sharing options...
GP4U2NV Posted April 11, 2009 Author Report Share Posted April 11, 2009 darn I was hoping you'd say less than what I have found them for. I found the 1 inch bolt on billet with the lugs for $75 a pair but have to purchase 2 sets (4 total) Quote Link to comment Share on other sites More sharing options...
webxfx Posted April 11, 2009 Report Share Posted April 11, 2009 Can you use 2nd gen rear struts and somehow use the 1 gen top mount? looking for a cheap way of lowing it. Quote Link to comment Share on other sites More sharing options...
GP4U2NV Posted April 12, 2009 Author Report Share Posted April 12, 2009 No you cant...... The 3 bolt mount strut uses a large spring. Quote Link to comment Share on other sites More sharing options...
webxfx Posted April 13, 2009 Report Share Posted April 13, 2009 No you cant...... The 3 bolt mount strut uses a large spring. Is making 3 new holes a smart idea? as anyone ever tried this? Quote Link to comment Share on other sites More sharing options...
GP4U2NV Posted April 13, 2009 Author Report Share Posted April 13, 2009 I looked into doing that exact thing. The reasons that it cant be done are: -the strut cap is not large enough to fit the 3 bolt mount -the strut cap is not strong enough to hold the extra stress of the spring (noted people are doing coil overs) Quote Link to comment Share on other sites More sharing options...
