G Body front suspension
Is there any consensus about what should be done to improve G body handling?
I have some Gen II Firebird front spindles; can those be used to improve geometry? I already have a GN front sway bar and an aftermarket 1" rear bar plus boxed rear control arms. But the front end is supposed to be no better than '64-'72 A body. |

I must tell you that I'm NOT an authority on suspensions. That said, it may be helpful if you will say how you intend to use your car. Will it be a daily driver, road cruiser, show car, drag racer, auto-x/road race, etc. Do you have a maximum budget? A final point, remember that the G-body factory F-41 suspension (and braking for that matter) is at best 25 year old technology.
IMHO, the factory f-41 would be real good for a daily driver or cruiser. Doug

I am going to install S-10 front knuckles to utilize the dual piston caliper and the 1" bigger rotor and a third gen F car 36mm front stabilizer bar and poly bushings. I will be also trying to stiffen chassis by welding in gussets and boxing control arms also.

Have you looked at the SC&C body bracing kits. The front triangle brace has been used by a few with very good results.

The car is a daily driver. Sometimes I like to take exit ramps and corners at the limits of adhesion, something I'm reluctant to explore as it is right now. It has stock springs, the ride quality is very nice. I have some Moog Cargo Coils I'm mulling installing in back. Global West has some upper control arms which are advertised to improve camber but they're near $600. I'm running 215/65R15s all around right now.

The front end parts of your G-body is the same as the 70-81 F-body cars. They use all the same parts. So if you go looking for parts to swap into it look at those parts. Keep in mind the parts fro the 70-77 F-body parts are the same as the 73-77 A-body parts to. &8-81 F-body uses a different size bearing but will also work on your car if you use the different front spindle bearings. But all the parts will interchange.

No Rex, All the parts are different. What you probably were thinking is that the 1LE spindles and rotors is a common mod. That mod makes the front track wider and doesn't help with bump steer. There is no cheap way to make the front end on the G-body perfect. An expensive one is here: http://scandc.com/new/node/742
I have done all the common stuff to my GP and its not bad/not great. I think modern rubber is the next thing to do (no 15 inch tires). FYI, when looking for all the different bracing that the G-bodys The later Grand Prix's have most of it installed from the factory. So, look at those in the junk yard for braces. |

Mr Twister, you are correct about the parts interchange on to the G-body (and the tires)! android 211,,,I believe in the old saying:"fast ain't cheap, and cheap ain't fast"! IMHO, the very best thing to do to your daily driver is to buy the best shocks you can afford (like maybe a Bilstein, etc.). Then, the best tires (and wheels?) you can afford. With out shocks and tires, your new suspension parts won't work at their optimum!

Well there is something to be said for going fast over bumpy roads and not having the fillings shaken out of your teeth. The car is a 87 Cutlass with a 500 Cadillac installed. Aluminum intake. Regular Cutlass 307 V8 springs have the front of the car sitting at stock height. I have completely rebuilt stock suspension front and back. Monroe Sensatrac shocks. Great ride with a bit of initial heeling over on hard turns which is controlled by the better than 1" front and rear bars. I know I need stiffer springs all around but it also needs improved front end geometry.

I knew someone out there would know exactly what to do. The car is already fun to drive, everywhere you go its just a tap pf the gas to get up to speed. Passing is a thrill. It has 2.73 gears so freeways are easy cruising. I just want to be able to throw it around a little.

The G body uses the same suspension as the 2wd S 10. That is why the 98-04 S10 2WD Blazer spindles and brake swap is so popular.
