Well I'm gonna be putting in my LCAs this weekend since I've been getting vibrations around 15 mph-20 mph a few months after installing the sportlines(yeah I'm dumb for letting it go so long). How much shorter did you guys make your LCA compared to stock when you adjusted them to the specs? I have an automatic if that matters.

 

Did you get lca relocation brackets? The only real reason for adjustable control arms are to adjust the pinion ange? I think

 

Yeah I need to adjust my pinion angle since I'm dropped so low.

 

Generally yes, but can be used correct axle position as well. These cars are built with tolerances, so there are permissible variations from optimum.

The installation would also benefit with the BMR LCA and UCA position brackets to correct the rear linkage instant center. With the car lowerered, the instant center lowers more, with the end result the rear wants to squat more under accelleration.

 

Yeah I'm prolly not gonna buy all that other stuff. Just looking to figure out how much everyone else with LCAs and sportlines adjusted their control arms.

 

I have equipped adjustable lowers and solid upper control arms from BMR. But I cant seem to find a shop who have a a measurment angle device. I've been having this huge vibration in my car when I go over 95 mph especially when I hit 140 the car just wants to flip..

I have an aluminum driveshaft ... any help here plz..

 

saud buy and angle finder and adjust yourself. isnt hard if you take your time

 

How do I put it and at what angle it should be ?

 

This is information only applies to 1 piece driveshafts!

You're going to end up killing yourself! You need to remove the driveshaft from the transmission and lay an angle finder vertical against the mounting surface. Record this angle. Now measure your pinion angle the same way. Adjust your control arms so the pinion angle is 1 degree less than the transmission. If the transmission anlge is 2 degrees, the pinion angle would be 1 degree. Your measurements should be done with the car level and the suspension at ride height. None of these measurements are set in stone and not all cars are the same.

You can measure the pinion flange angle by laying the angle finder horizontall across the bottom of the flange.

The black line I drew on the above pic shows where you want to put the angle finder, make sure it's sitting flush. The stock driveshaft is connected in that pic and is on the left.

Here's what an angle finder looks like, should look the same where you are at.

thanks guys.... this really helps

 

Did you guys notice in increase in noise coming from the LCA's after lowering the car? Mine now make a creaking noise and I believe this is due to the angle of the LCA's. They are now angled upward instead of level. I do have LCA brackets, but they haven't been installed yet.

 

this is a great article.

im confused a little...do you need relocation brackets if you have adjustable LCA?

thanks!
