I am planning to install a complete system in the trunk (subs, amps, etc.) and am worried of the rear sagging substantially. I would like to know whether getting either tokiko illuminas, or koni adjustables and setting them to one of their stiffer settings would alleviate some of the sagging, compared to non adjustable shocks.
Also for people that have installed full systems in the trunk....how much sagging have you experienced. I am currently running H & R OE's.
thanks in advance

 

Correct me if I'm wrong, but shocks don't have much effect on ride height. The car is kept up by the springs, not shocks. There are perches on the shocks (ie koni) that allows you to play with but the diff is like 0.5 in. If you are worried about sagging with system, you may want to get some coilovers.

 

Well, it will help your weight balance. The TL is at 62/38 if I'm not mistaken.... damn FWD....
