Resurrecting this post.
Finally got my suspension upgraded and I did a bit different than what I posted above.
Today I finished installing
Eibach Springs (1" front 3/4" rear drop) from MarylandSpeed.
Monroe "Sensi-Trac" from Advanced Auto (210 for all around shocks/struts) with strut mounts/bearings(180ish total) from GM.
Youve probably seen some sh*t talk about the Eibachs. Don't listen. They are great springs for the price. And you also don't need to spend $500 on shocks. I went with regular Monroe shocks and they're fantastic.
Springs - 250
Mount/Bearings - 180
Shock/strut - 210
TOTAL - 650 ballpark. Compare that to other brands and I could have spent 100s more.
(I also installed new EBC Red pads all the way around - 160)
Project difficulty (my opinion) about a 6.5-7.0/10
Total time (in labor) approx 6 hours(over 2 days waiting for parts ORDER MOUNTS/BEARINGS! THE OLD ONES AREBAD!!!!)
some of the difficult points were:
-getting to the right rear shock bolt in the trunk, the filler tube to your gas tank is in the way. could remove that to ease installation but i didnt.
-holding the shock/strut main shaft still while trying to tighten/loosen bolts. the little fitting on top isnt an exact wrench size, theres a special little tool thats supposed to come with it but mine was missing.
-have a decent spring compressor
-have a extra set of hands
-disconnect the cv-axles at the differential not the hub despite what manuals say, to drop the rear (make sure to trq back to 37lbs)
-disconnect the rear sway bar from the middle bolt on the links to drop
-when reinstalling the front struts, make sure you get the sway bar link in the strut mount before putting the strut all the way up the tower
-make sure to set the spring in the front struts all the way in
-make sure to get an alignment after
You wouldn't believe the phenomenal increase in handling and stability from shocks/springs.
-You get a lot better acceleration as you have no wasted energy in saggy rear ends. I actually felt the inertia in my own neck while I was driving. And the wheel hop was non-existent. It feels like you gained 50hp.
-You get better deceleration from the nose not diving like a front loaded sled. With my new brake pads that car is stopping on a dime. It comes down from 80 effortlessly without having to smash the pedal
-You get tight responsive handling and a lot less body roll (sway bars next). the lower center of gravity is noticeable. you can put throttle down a lot earlier in the turn and not worry about the front sliding or rear coming around.
I cant even describe it. Its like a whole new car that feels like it lost 500lbs. There was almost no sacrifice in ride comfort. you can feel the bumps a little bit more but its not uncomfortable. it generally feels more "grounded" and i feel a lot more confident at speed. no sloshy weight transfers and oversteering.
the stock suspension was so saggy that even though it was a lowering kit i literally stayed the same height in the front and barely dropped a fraction in the rear.
go faster, stop faster, turn faster. you cant beat a good suspension.
I was going to get a cam originally but decided on suspension first and im happy i did.
I highly recommend at least shocks/springs to all GTO owners and you dont have to buy the high price items to get high performance.
Ill post pictures tomorrow when the sun comes up =]
