I have my alignment specs attached after eibach pro kit install. I rotate my tires every 5K and want to see if I truly need to install camber arms? Its very expensive and would like some input before making decision. Also, still trying to reduce throttle lag in paddle shifters. I have car tuned with Uprev but it didn't do much for this. I was searching and saw many with grounding kits. Can anybody attest to whether these will solve this issue, and if so which are the best to use as well as are there any negative aspects to installing these. Advice sincerely appreciated. Thanks

 

I don't believe the specs on your alignment sheet are correct, it states -2.5 to -1.5 is the camber spec range.
I'd look into at least a rear kit, those aren't that expensive and they're easy to install. Much cheaper than new tires every year or less.

 

Anybody else????

 

what BLNEWT said, rear arms may benefit you here. Try to have it checked for free by a few places or atleast one other, most of them check it for free.

 

The alignment sheet says "modified specification"... that seems a bit unusual.

 

I just bought lowering springs and rear arms because everything I researched said getting rear arms with springs was a must. Not sure if that helps you at all but I would say yes, get rear arms at least.

As far as the paddle shift lag I would say 100% the grounding kit will help that. I highly recommend it and I can't find any negative aspect at all, it removed the lag I used to have. I looked at the DIY section and made my own kit for under $25.

 

Eibachs do not require camber kits. I have been running them for quite some time and after an alignment brought them back within spec. No unusual wear or any problems. Anything lower then Eibachs I think is recommended, but typically only in the rear. I'm going coils next week and got the rear kit. It's not too expensive, if it bothers you that much I would just invest in the rears.

 

With coilovers you are going to need a front and rear kit if you're planning on going low. Your front alignment would definitely be out of spec.
