A stout street car can tear the LCA mounts out of the frame. If you’re seriously racing the car and have sticky tires, welding in gussets is required, which is beyond bolt-ons. You can rip off a few good 60’ times with only bolt-ons but it’s only a matter of time before the grenade explodes.I guess i should have worded a bit different. I'm wanting to know what the G-Body is capable of sixty-footing with just bolt-ons for suspension. Let assume motor/trans/rear/slicks are all up to the task...?
I'm going to start another thread with my setup and what i'm trying to accomplish.
Car has a 800 N/A hp BBC with power glide, 3800 stall, trans brake, 9" rear and 275/60R15 MT ET Street Radials. Got it from a guy that street raced it. Has alot of good stuff but also alot was overlooked. Car currently has UMI non adjustable rear control arms and single adjustable upper's. No frame bracing that i can see and rear frame has not been notched. I know the suspension will need work which is why i'm asking. I have no experience with G-Bodies so i'm asking what they are capable of. I'm no welder and i don't have alot of $$$ to throw at the car. Trying to see what can be done before deciding on a course of action.Slick or radial, weight, trans brake or foot brake, NA, turbo, blower or nitrous all makes a big difference.
If you are asking here I assume the car is slower than 11's, and yeah, it can do it, but you might need to take a look at instant center depending on tire height, ride height...
I'm sorry bro, i forgot to mention it has a 6pt roll bar. I'm aware that will need upgrading as well....With those credentials it sounds like a solid high 8 second car with a sorted setup.
Depending on the 9" it might already have lowered LCA pickup points on the housing. A stock G body is set up more to 'squat' for slicks rather than 'lift' like a drag radial wants.
No cage I assume? That's going to hurt. A G body really needs some type of chassis reinforcement once you get sub 10's.
If you are crazy enough to run 8's at the track without a cage, (maybe once until they kick you out) and want bolt ons, UMI also sells a LCA to UCA brace that helps stiffen things up. Nothing wrong with UMI adjustable uppers and non adjustable lowers as long as they don't have polyurethane.
I'm far from the expert as I have a high 10 sec capable heavy G body without a cage but I am at the point where I need to address chassis stiffening and making all my suspension bushings heim (or solid) due to tire shake issue. Low 9's or high 8's NA it's 100% going to need a good chassis.
