what kind of 60's improvement should be expected from steeda lca's ans uca's
 

i just ordered the steeda aluminum lower control arms and the heavy duty uppers....what kinda 60' improvement should i expect from this?

i certainly hope i havent wasted my money by investing in these pieces

They will help rear bite a little bit and they do help to hold the axle more firmly than the stock arms and are good pieces for a street driven car, but the difference in launching will not be dramatic. In order to make a big difference you would need to get drag springs and dampers or sticky tires.

As stated above, it will be noticed with DR's or slicks...initially you will notice the "sway" is dramatically reduced.

ive got eibach springs not drag springs but do they help....and what are dampers....i have both the lca's and the uca's on now and it seems to hook alot better on the street havent tried it at the track yet though....how many tenths should i expect to knock of the 60'....i would like to pull 1.9s is this possible now?i mean consistantly
