Heidt's drop spindle and A-arms

[Dads502]

Does anyone have experience in using the Heidt's 2" drop spindle and their tubular A-arms on a 69 Camaro? I'm using a stock subframe and most A-arm manufacturers require modification to the subframe, but Heidt's claims theirs is an easy bolt on. On the drop spindle, I am currently using Hotchkis 2" lowering springs in the front with stock height spindles. If I go with the 2" drop spindles, will the front end drop even lower than it current is, or will it just change the geometry of the front suspension components?

Who told you that other tubular control arms require frame mods?
They should all bolt on with no issues. My personal recommendation would be Global West, Detroit Speed, or Speedtech arms, as they will actually give you increased caster from factory. The heidt's, fatman, and similar brands are nothing more than a tubular emulation of a factoy arm, offering no benefits other than looks. Heidts and Fatman both offer narrowed arms which is the opposite of what you'd want to get better handling.

On the spindle- Are you talking about their standard 2" drop spindle, or their new 1.5" taller two inch drop spindle?

The taller spindle will increase the camber gain, which is a great thing as tubular control arms by themselves will not give you much in terms of increased feel.

The bad news-

A 2" drop spindle causes lots of tie rod to rim clearance issues, especially if you go over 6.5" wide rims.

An alternative is our new AFX spindle. It onlys has 1" drop, uses a C5 sealed hub with wheel speed sensors, and is made from 6061 T6 aluminum. It was designed for handling in mind. You can find more info about that on our website, www.t56kit.com

So between the DSE, Global West, and Speedtech upper A-arms, how would rank these in terms of performance and quality, starting with the best one first?

[Teetoe_Jones]

Performance wise, GW is at the top with the most amount of initial caster settings, followed by DSE then Speedtech.
Quality, DSE can not be beat, GW is second, with Speedtech third.

Thanks Tyler. Do you have a 69 Camaro, and if so which ones are you running on your car?

[Teetoe_Jones]

I have a 68 Camaro, and I'm running none of them.
Most of the cars that come out of my shop have either Global West or DSE arms on them.

I have the heidts tubular A-Arms and they have more caster built into them. I talked to the guys there quite a bit. They are good guys helped me out alot and the arms look great.

They do? How much exactly?

They claimed it had 3 degrees of added caster. The guys at the alignment shop didnt believe me and I had to call them to verify. But its about 3 degrees.

How do you sugest lowering the car 2 or even more then 2 inches with wider wheels??
