Time to do some part buying so I have plenty of stuff to do when late spring rolls around. My main focus will be the suspension, as I believe it is a major support modification in whole. If you wanna go fast, you need to corner well and brake hard
I've been looking at trailing arms as my second suspension purchase, first was all 4 timken hubs.
Basicly, I need help figuring out which is the best to buy. I want only the best for my impy ofcourse Price is not a issue. I've done some research and this is what i've gathered. I'll be getting them powdercoated, along with everything else suspension wise.
ZZP Performance $119.99
Weight per arm is unknown, but they say they are apparently the best in the market. (I feel like they are just saying that)
Material is 4340 Chromoly
HT Motorsports $ ??????
Energy Suspension Poly Bushings
Drilled/Fitted Greasable Fittings
Weight is 8 pounds per arm
Material is Steel
W-Body Store $49
All I know that it is made of steel. Also it is a box shape? Is there any difference
in comparision with boxed vs. tubular? Doing some research on the forum, they come shipped with a Dorman sticker. I suppose this is true because of the price,
compared to the other aftermarket ones.
EDIT: Just got a email from them saying it is 1" thick, they are guessing 9 to 10 pounds each arm. I asked them if they have poly bushings with grease fittings and they said: No, these are intended to be a heavier duty stock replacement. There's not a lot of benefit to using poly bushings for this particular arm.
BMR Suspension $129.95
Fluted Poly Bushings
Weight per arm is unkown
These are all the aftermarket trailing arms I could find, I know of the GMPP but they are discontinued. Also, the replacement ones such as Dorman, Raybesto, MOOG, ACdeclo, ect... doesn't seem the right way to go if i want performance handling.
So obviously poly bushing and greasable fittings seem like a right way to go. Is lighter better.. is bigger the tubing better? Also, wtf is with the "boxed" arm?
I believe the GMPP trailing arms have been discontinued. That being said, I'd just go with the cheaper boxed trailing arm. Anything is better than the stamped metal trailing arm on the car now (you can flex it with your hands when it's off the car). I'm also pretty sure that a boxed trailing arm is what is on the Impala now. Either way it's a relatively minor gain compared to adding stiffer sway bars and a rear STB to the car.
Protip: If you don't know what you're doing, don't do it.
Yeah, if i could get my hands on the gmpp that would be great but it would be pretty rare to find them. So it seems like the majority of people go with the boxed design... So there would really be no point of getting the higher priced ones? I would think that a thicker tube, and poly bushings would be a great benefit. I know it wouldnt be the biggest in suspension upgrades, but eventually it will all add up when I buy the other parts. Yeah, I saw those on rockauto and that's definetly the way I would go if I buy dorman. I just want to do things right the first time, yah know?
