LCA install
 
Is it a trade secret to install these? Why no tutorials online or anywhere? This car noob can't do shit right now.

not to be a ****, but the install process is very straightforward and if you're capable of doing it yourself, it will be easy to see what needs be done by getting under the car and looking at the control arm.

1. Jack the rear of the vehicle up after breaking the torque of your rear wheel lugs

2. Take off the rear wheels

3. Take off the bolts connecting the LCA to the strut, hub, sway, and chassis

4. replace and bolt to spec

Also, view the FSM and it will tell you everything man

a few bolts, if you've done coilovers it's simple. Depending on the lcas you bought you might need toe arms to get the toe straight. I just jacked up the rear and got it done.

Stance adjustable lcas

A normal LCA seems pretty easy, but I got a set of adjustable LCAs from stance and I'm not sure if it'll be as easy. I'll give that link as read. I also need to figure out how much to torque it

I just googled LCA INSTALL BRZ using google.ca. It's the first link that pops up

Just make sure you get alignment done as soon as possible after install, and also helps if it's nearby.

I had my Buddy Club LCA's installed at Buddy Club's facility (they wanted to test some things out). They eyeballed the Toe, and used a measuring tool for the Camber.

After I drove off, the car was nearly uncontrollable at over 30mph, and I could smell my tires wearing off. I had to nurse the car over to an alignment shop.

Results showed the Toe was grossly off. = /

Koa 12-03-2014 05:42 PM

Stance LCA's use the same exact mounting points.

The only differences for Stance is their geometry, part materials and end joints.

I thought it was best to tighten the control arm bolts(not endlink, coilover bolts) with the suspension loaded? Didn't see that step on the moddit link.

Word.

I installed my LCA myself, didn't adjust to recommended settings as I didn't have wrenches big enough so it was at it's shortest length.

My alignment shop luckily was less then a mile down the road, but for that mile it was scarry. Toe was so off you could see it, my traction control would pop on going around a 90 degree bend at 10 MPH. The tires would screech when making small turns and the back end would shimmy back and forth going straight.

When I had the alignment done my toe was at 4 Degrees of toe out! Made for a very exciting drive.

I believe this is correct. That is what I did, Just shoved the jack under the hub and compressed each side.

Jack up car safely.

Remove 4 bolts, swap LCA, reinstall 4 bolts. Repeat on other side. Torque all bolts to spec.

No offense, but put it this way. This is one of those installs where if you cannot figure it out by looking, you REALLY should pay for someone to do it for you. This is not an entry level DIY like an oil change (which will have DIYs, because it is entry level).

Thank you. The install is very straight forward, I was talking more so what specs should I tighten it to? I couldn't find a guide that explained that. Should I just do it til it's tight or...?

Cool. Thanks dude! Probably do it up on Saturday when I got the time then! Seams easy enough!

Yeah that's what I'm scared of. Luckily the firestone is like 3 miles away for me

If you're unsure, OEM.

Or, tighten by thread size.

All nuts are 59 ft-lbs except the sway bar end link which is 28 ft-lbs. I usually leave everything snug except for the nut near the hub. I torque that one down since you can't really fit a torque wrench there easily with the wheels back on. Then lower the rear onto ramps, bounce the rear a couple times to let the suspension settle, then torque everything down.

This install is pretty entry-level imo, and has plenty of DIYs :P

/sits down

adjust to the length of the stock LCA (line them up side by side so you can look through the holes, or actually measure mounting points)

seriously this is pretty basic. you sure you know how to operate a jack?

First tuner, only car, big commute. don't want to fuck things up.

in that case, you are already screwed.
i tried to daily drive my project cars. unless you are loaded and/or dont care, its going to be a challenge.
mileage will suck. parts will break. any installation MUST be finished before work the next morning...
i had a 94 240sx and then a 98 camaro Z28.
after a blown transmission and overheating problems on the 240, i battled all kinds of stuff breaking on the Z28 including a water pump... that's before taking into account the $30 a day in gas to feed the cam'd and tuned LS1...
i have neither now and decided to just get a modest/dependable daily (in this case my 2013 accord sport sedan), and my project AE86.
mine is an extreme case though. i am commuting 70 miles each way, and "calling in sick" is not an option when you work on a US Warship.

long story short... you might be digging yourself a hole here... be careful.
