What rear suspension first?
Hey all,
84 T/A
Car is lowered 1.5" on Hotchkiss lowering springs and has hotchkiss sway bars and poly bushings already done. Wow, 7 years ago now..amazing how the time flies). There is more done to it, but that's it for suspension in the rear. More info can be found on my link in my signature on the whole car.
I've got enough money to do wither LCA's and founder relocation brackets or an adjustable panhard bar. Not enough to do both. Where should I start? Any advice is greatly appreciated.

Re: What rear suspension first?
Well if its lowered I'd say get the lcarb and if you get the brackets might as well do the LCA while your there . I'd say torq arm next.

Re: What rear suspension first?
Looks like it's LCARB's and LCA's. Why the Torque arm before the Panhard?

Re: What rear suspension first?
torque arm will help with wheel hop and takes the stress off the transmission if you do it like I did with a crossmember mounted torque arm and ive been told it helps with acceleration coming out of corners. honestly the only reason I even did a phb was for adjusting the axel side to side because I went aftermarket rear and I did all three at the same time.

Re: What rear suspension first?
I was looking at that, I just don't have the $400 right not for that set up. It's on my "to do list" however. I was just wondering where to start and looks like LCA's and LCARBS are the way to go.
Re: What rear suspension first?
I see it's time to preach to all the new members on here give bad advice.
Did anyone care to look at his car pictures or read his SIG? Nope.
#1 on any car ....TIRES. Why? The are your connection to the ground. They always need to be in good shape for the car to roll safely.
#2 for the love of god, SHOCKS people. Shocks ate your most primary suspension function to keep the tires in contact with the ground...AND...they control the chassis weight for safety and control.
Lca's, relocation brackets, sfcs, sway bars, tq arm, panhard, etc... Are all crap to a car that does not have the basic #1 and #2 in line of importance.

1. Cooper Cobra GT's with less than 1000 miles on them.
2. 13 year old Monroe Sensatracs' that do leak just a little and probably need replacing. However, I want Koni's but they're out of my price range at the moment and I don't know where I can get a full set of shocks/struts for $300 or less unless I go back to the Sensatracs
So I was looking to get some insight on what to get next.

Re: What rear suspension first?
If your car is lowered, how did you keep the axle centered with the stock panhard rod?

Re: What rear suspension first?
The LCARBs are good for eliminating wheel hop. If it were me, I'd get some good shocks and the adjustable panhard rod, but then again I don't even have a panhard rod anymore.

Re: What rear suspension first?
I could probably afford to do rear Koni's but nothing else right now. No way can i afford the $460+ for tje fronts alone. Maybe this tax return plus next year's lol. And I Have to limit myself as i prep for a possible move later this summer.

Re: What rear suspension first?
Save your money and do shocks and struts. The other parts will not benefit you at this time and depending on bushing material, may actually hurt you.
Keep an eye on the classifieds, you can usually save money on almost new parts there.

LCA, PHB, relocation brackets, that stuff can wait for way down the road.
I would put it like this. Konis are like putting insulation in a house in Alaska that doesn't have any insulation. The other stuff is like putting curtains over your windows.
I've done a lot of suspension stuff over the years. But nothing has made as much difference as the shocks and struts.

Re: What rear suspension first?
I would without a doubt say buy the rear Koni shocks and nothing else at the moment. They are worth the money. Once you get them put in you'll see a world of difference between the front of the car and the rear of the car. Down the road, maybe 6-8 months from now, you can do the front Koni struts. They're the expensive part.
