Whiteline Rear LCAs and Rear toe correction

[whataboutbob]

I've been reading up on this over the last couple of days. It appears that swapping out the LCAs and toe links may have an impact on the toe-curve for the rear of the car. Right now I am still on the factory structs with RCE springs. I mounted the lower eyelet of the struts in the outermost hole on the LCA.

With this configuration when the rear end is compressed over uneven surfaces I am experiencing what I can only describe as "bump-steer". (Yes I know that term is used for the front suspension).

I am going to move the rear strut lower eye to the center position and see if it changes this behaviour.

Thanks for testing this out for all of us! Gorgeous lca's!

Put the car on jackstands last night and found out that the bolt holding the toe arm to the subframe on the driver's side had come 4 turns loose. Tightened it up and the drive in today had none of the odd bumpsteer behaviour. I'm going to have to keep an eye on these bolts to see if they continue to come loose.

I'm pretty sure these are one of a very few limited sets that were released for testing.

First AutoX event today on them. -2.5 camber in the rear is too much. Car was WAY too tail happy. A little bird told me -1.5 is the magic number, time for another trip to the alignment shop.

We finally have these in stock!

If you want a setup that really lets you dial in your rear suspension these LCAs along with the rear control arm toe adjustment will allow you to adjust to your heart's content.

The LCA has 3 lower shock mounting positions and 2 swaybar endlink mounting positions.

I've had these on the car for over a month and have had NO issues with the camber adjustments coming loose. I also haven't noticed any additional noise from the rear suspension beyond what was present after the subframe and differential inset bushing install.

These things work and look sexy!

are they lighter than the stock LCA's and toe arms? since their made out of aluminum it would be nice to drop More un sprung weight! I was looking at those for that reason but I couldn't wait so I went with the standard cusco choice. How are easy is it to adjust the LCA's the cusco were kind of a pain hard to get a wrench in the tight clearance on the subframe adjusters sit to far in.

do you have any pictures of them with the wheels on the car?

Here you go.

What about bob... Curious I see you're using last outward bolt position for strut, why so?

I was told that it would give the car a slightly lower ride height and better turning behavior. I'm still on the factory struts and RCE springs so this is really my only dynamic ride height adjustment on the car. I just had an autox practice day here in SD at the Q and the car felt great on course. I was thinking that -2.5 in the rear is too much, but now I'm not sure I still feel that way. I need to leave it be for a few more events before I think I can come to a good conclusion about the current rear camber settings.
