Default Suspension upgrades 69 Lemans/GTO

Looking for opinions on front suspension parts, what brands do you prefer? Pros and cons to certain brands? Any personal experience!!! I am refurbishing my front suspension on my 69 lemans, bushings are shot, needs inner&outer tie rods, center link, idler arm ETC… I’m looking to replace the original parts with something robust and something racey. Any tips will help. My goal for the new year is to get my car running top before the 2025 is over

Proforged parts. Although from overseas they are of very good quality. And more importantly, they fit correctly.

Moog used to be the go to for suspension parts but their parts now seem to be made in India or other Asian countries.

Stock sizes are just fine. Not to much clearance for oversized (robust) parts.

If you are lowering the car, you may want to look into bump steer tie rod ends.

Honestly, stock arms rebuilt with new rubber bushings, and a .5" taller upper ball joint with a modern alignment, quick ratio box and front/rear sway bars handles and drives great.

I'm working on a 69 Lemans convertible and are trying to take a middle of the road approach to improving the handling. I've installed UMI upper control arms with the tall ball joints (UMI 4056-3). The original front suspension geometry is poor on these cars and the UMI 4056-3 is the most cost-effective improvement I found. I'm reusing the lowers with Energy Control Suspension Polyurethane bushings (3.3168G). I'm planning on using a Hellwig front sway bar but have not purchased it yet. I've installed the UMI 1" lowering springs.
I need to start a separate post on some issues I'm having. For one, I've got a 3/4" ride height difference, left side being higher. Second, I've modified the front fenders to clear the 18" 245 tires I'm running. 68-69 GTO / Lemans front fenders have a shape which will contact the rear of the of a wider tire.

Was the clearance issue due to width? Or because the car was lowered?

I did a full global west front end on my '67. Uppers, lowers, springs, 1-1/4 sway bar. I also put in a borgesen steering box and good shocks. Taller upper ball joints. Its night and day difference from worn out front end and drag springs that were in there. It handles much closer to a modern car.

My clearance issue was due to wider tires.

Are you using stock wheels? You may need to use an aftermarket wheel with more backspacing to alleviate tire rubbing issues on the back of the front fender.

Not looking to lower the car, I have the rear jacked up a little and the front is stock height. Looking for a 70s look
