I ended up having to use the Pfadt bolts on the rear, because I couldn't get the rear to lower to match the front. The gap was huge to me. The stock bolts worked just fine in the front. My splitter (Z07) in the front is 5.25" inches off the ground, which clears my drive okay. Did a four wheel alignment afterwards. Behaves well on the track and street.

Lowered on stock bolts all the way around. Echo what others have said, just have to be a bit more careful of scraping. On an "aesthetics" side I think the wheels finally fit the arches like they "should".

Bosh
I know you track your car a lot.
How much did you lower? Did you trim the rear bushings?

I lowered mine about 3/4".
Toke it to a specialty alignment shop to re align. I was there to watch the settings. By lowering the car it thru the alignment off.. Spent $60.00 to re align. Should save that much on tires

Adept but ignorant
I am comfortable with the technical idea, but don't want to guess who is experienced in doing this. I have a very competent alignment shop for 'after'.
How hard can it be? Do you count turns, or…
Thanks

Question for you guys in the NY area that lowered your cars.... Have you noticed that you are bottoming out a lot more? I am really wanting to lower it on the stock bolts, but am afraid that I'll wind up cracking the front splitter.

Last Friday I was in a caravan of 16 cars with only one lowered. Each car went over a very large uneven lane on the highway one after the other. The only car that had a problem immediately was the lowered car. 3 bent rims and screwed up tires. None of the tires ruptured or went flat but it was immediately apparent something was wrong.
I can't say with absolute certainty it was the fault of the lowered suspension but it stands to reason that the reduction of the compression stroke of the suspension may have had something to do with it.

Lowered on stock bolts, been to five autocrosses and have over 4000 miles on the car including some spirited driving in the Smokey Mountains and Touring Laps at the NCM Motorsports park (up to 108mph) - no problems here - yet...
