These are BMR adjustable Lower Control Arms LCA they are attached at the axil with the Lower Control Brackets LCB which is between the LCA and the axil. The LCA is usually affixed to the axil directly. This added space creates a virtual triangle along with the Upper Control Arm UPC. When the LCA is affixed to the axil it is a straight line and can be deflected, bent which absorbs forward momentum and promotes un-sightly wheel hop.
The LCB and a stronger tube LCA create a strong triangle and plant the tire and lessen wheel hop, which propels you forward. They're about $109 for the White-line you see here or $150 for BMR. Also those BMR LCA's have spherical ends at the axil and poly at the front.

very nice!!

 

For better ETs at the track.

LCA's to eliminate wheel hop and aid in traction. $100 mod
drag radials so you have no traction issues. $500-$600
Longtubes for more power. $600


These 3 will offer the best bolt on mods for a N/A car. With a 5 speed your gonna need to drive it like you stole it with DRs to get into the 12s. Speed cost money and is very addicting........look at my sig. LOL

Congrats on the new gears.....they do make driving the car awesome.

 

Here you go

Those are Prothane replacement bushings. At that price, I'd suggest going with a quality LCA and skipping the bushings though.

 

+1. replace the LCAs, and buy some relocation brackets at the same time.
about $100 each, super easy to install, and way worth the upgrade.

 

4.10's was the best upgrade to my car so far.

 

Installed my LCAs in the driveway in less than an hour today. Gears tomorrow

 

whats your times in a quarter mile? love 4:10s

 

I'm mid to low 13s consistently but I spin through my '60 (good old nitto 555s lol)...With better tires and a good launch I'll likely see very low 13s (possibly 12s) and that's with my 4.10s/suspension mods I have going through an auto.

PM me if you need any parts. I can hook that up for you.

 

With CAI, Brenspeed tune and 4.10s I was running 13.4s on street tires and auto trans. With a 5 speed you can dump that clutch and get better times but you gotta beat on it to really get good times.
