I have used Eibach in the past.. (NOT SPORTLINES) and I have had a problem with poor ride quality.. Now when I say that I dont mean.. its hard.. I mean it SUXS BALLS..
When I build a car I don't mind a hard ride, I like to feel the road and I like to feel when it hits back.. but the standard blacks are jsut IMO no better then stock coils but lower.. they just don't help the handling IME at all.
NEW UPDATES...
Got rid of the racing harness WOOT WOOT.. got a stock seat belt back in the car.
Also pulled the stock manifold and down pipe tried to install a 4-1 header however it did not fit the stock cat so I put the stock mani back on... sold the header so I am happy.
Installed a new horn (now I have a horn WOOT
Soon I will have what I think to be an OBD2 valve cover I am going to paint up and put on the car (next weekends project)
I also moved the stock headlights out for 9005 (high beam) 100w equiv bulbs in all 4 positions.
Things are turning around for the teggy.. I am happy.. and as of now.. not breaking the bank
