Default Global West "extended" lower control arms...

Has anyone tried these extended lower control arms?
http://www.globalwest.net/corvette-f...lover-c-3.html

I spoke with the company and they stated that the extended arms lower the front of the vehicle 2" while allowing full travel of a coilover. The rep also stated that with their standard lower control arms the ride height can be lowered 1-1.5" but will lose shock travel. I am not sure they will clear my 18x8/4.5 backspace with P245/45's?

Looks really close!

Thanks, B-R

I have them but am body off restoring the car right now. Just hung them on the chassis a couple days ago. Really nice stuff. Going to run Ridetech coilovers with them. I am running the Ridetech system in the rear but didn’t do the front mainly because I am staying with 15 inch road race style wheels and tires and want my stock brakes and already had Wilwood D8 6 calipers. Got the Global upper arms also. Really beefy, strong arms. Definitely heavier than stock stuff, and I hear their bushings are the best around. Sorry I can’t give you any driving feedback yet.

Hmmm. Those look interesting. I don't like the mandatory brake upgrade with the Ridetech arms. What I did for now is I custom ordered threaded body Viking shocks with poly lower mount and mounted them on the bottom of the stock control arm. You can do this with a regular lowered coil spring but not the semi coil over. It would be easy to use these same shocks and upgrade to the GW arms. Excuse the dirt this is still work-in-progress.

I think from memory that craigh has these and has some discussion of them in his build thread?

Neil, I'd recommend running longer bolts with additional nuts above the control arm - I stripped some of those threads on my lower arms using Bilstein Sports.

Will do. That was just a mock up.

I think you misunderstood what the tech was saying. These A-arms don't automatically lower your car 2". They allow you to lower it 2" and still have full travel of the coilover. The ride height is set with the coilover; not the A-arm. "The shock is mounted lower in the control arm extending the shock length so there is more travel at the lowered ride height."

I believe that's how instructions show also? Don't remember.

Correct me if I am wrong, but I would think that the same size coilover in the y dimension; (length) has to have a certain amount of spring tension to keep the coil in place when suspension is at full extension. So given the same size coilover at the same tension the "extended" lower control arms would lower the vehicle the 2" as the tech rep at Global West mentioned??
(I would think to maintain the same ride height the coil and shock strut would have to be 2" taller/or a 2" larger unit)

Does someone know for sure?

Thanks!
B-R

I'm running a stock style spring, not the semi coil over. The weight of the car is not on the lower shock mount in my setup. I bought the threaded body shock so I can upgrade to coilover at a later time.

Yes but the ***** have increased resistance at the higher settings. I think I could adjust them in the softer ranges without dropping them. Stiffer settings may require me to pop them out real quick.

This is correct!

I decided to go with the standard Global West lower control arms for coilovers as I already have clearance issues! My side pipes are currently at 5 1/2" and will only be able to go down about 3/4" to keep from dragging them on every speed bump in town!!!

I have a C2, but as part of my build I’m going with 17x12 wheels with 335/35-17 tires, so I upgraded to C3 spindles and am using these GW ext control arms with Ridetech coilovers. The quality and adjustability is amazing. To the earlier question about the adjuster, it comes out the top of the shock and is easily adjusted from the engine bay. I’m using the Ridetech coilover set up in the back, but have not installed it, yet. My ‘64 will be lowered 2” all around.

The only thing I don't like and it could be a quirk with the car (no accident damage), is that the can alignment isn't perfect for coilivers or semi-coilovers! I thought above cutting the can, but instead am making two different top of can bolt on plates (one for a return to a conventional spring or take that off and put on a top full coilover spherical mount! I like the larger coil over springs, so I dropped the mount location slightly on the top mount, to avoid top of spring interference to the can! The extended lower, keeps me good on travel when lowered!
