Ok i have done a lot of reading and i don't post much because i really do try to search my answers but this i can't seem to figure out. Now I dont race much anymore not sure if its because of my young family with no time but i do drive my cars pretty hard for fun. Lets start with control arms. So I went to the 3 places i usually go for parts i see a lot of options and i find a lot of packages. here is what i was looking at

are these ok to use for 3 or 4 days a week of street usage? No racing just street. I ask because i see so many options out there.



Springs. For the past 3 years of driving my chevelle its such a bouncy ride even with new shocks. the ride is bouncy in the front because i have cut springs. I love the look and the cornering of the lowered suspension but i can't stand how bouncy it is. I am looking at some lowering springs for it but again so many options here is what i have selected

sorry for the long post

I see you've had no responses. I'm looking for info on control arms myself.
The "bounce" you say you have is most likely due to the shocks not dampening the spring. I've seen your racing vids on you tube, if you have drag springs in the front to get the nose up on launch, you will probably also get that bounce.
I have a set of lowering springs in my '69 with a set of Bilsteins at all 4 corners and it has a nice firm ride with no bounce at all, it's actually really a nice ride.

The goal of replacing upper control arms is generally to gain better alignment specs for improved caster which helps steering feel and stability. The speedway ones you showed have"improved caster" they don't say how much.. and I couldn't see the other ones cause the work firewall locked it out lol.

IMO, if you're not going to get improved caster/camber then ther'es no need to replace them. I am running the adjustable SPC uppers with a tall upper ball joint. this not only allows me to dial in my own alignment(not hard at all), but the tall bj corrects the camber curve, -those two pieces make a big difference. You might want to check out MArc at SC&C as he led me down the path of awesomeness.

Empty pick up truck effect.. Sounds like the springs.. Talk to Marc at SC&C...

Bounce would be the shock inadequately dampening the springs.....springs hold the car up and shocks control the ride....its that simple

[CSG]

Agree with Rod. You do need to get the proper front springs first though. If you could add enough rebound you can control the cut springs but do it right and get springs and quality shocks.

It seems to me that you would be best served to buy a comprehensive kit that is designed to work as a system rather than buying parts piecemeal and hope they will work together. For example, shopping for control arms without a clear understanding of what you want them to accomplish and what related parts you expect them to work with is a waste of time and money. Something like the ridetech Tru-Turn system is designed to solve specific factory suspension geometry problems and is engineered to work as a complete system. I can assure you that it will cost less to buy a kit like a Tru Turn and you will have a better driving car when you're done VS buying a collection of mystery parts from a number of unrelated vendors and hoping the parts work then having to buy more parts when they don't.

FWIW, the below arms come from Ground Up, in a Hotchkis box.

Good street setup for the street on these abodies are #550 front springs,good shock ridetech,1/2 tall lower ball joint,can run with a stock lower,or the whole ridetech street grip kit.
And yeah call mark!
