Your springs will settle.
2 fingers in the front? yuk.

Well better than the like 4 o 5 stock and the thing diving like mad when you hit the brake, arrgh. I barely remember that, from like year 1.
I started with Vogtland springs and then went to TEIN SS CO's at around 80K
So I have about 100K miles on the TEIN's.
What brand springs did you use?
I had wider rims but the rear ate tires like mad.
I got tired of it, and went back to stock after putting up
an online poll of which wheels looked better.
People like these C7 wheels. Amazing.
So, now I run stock tires sizes, which saves $$
and rotate so I don't have to replace rear tires more frequently than oil changes.
Sumi HTR3 only lasted 5K miles!
I should take the 240HP out of my sig.
I haven't done a dyno, but base on other people's dryno's
I'm guesstimating the power at the crank.
And I don't have ECU tuning, but pulley, header and entire exhaust,
+ removed supercharger muffler (huge plastic obstruction) and screens from MAF and throttle body. That all adds up to 40-50 HP over stock.
All that will cost you about...more than it's probably worth.
Pulley is about $700 to you + install.
Header is practically unobtainable. Contact Supersprint. Last I heard one sold for like $1300. Free flow cat, Remus muffler + welding? uh...another 1000+, plus labor. The other stuff if you DIY, free. Well not entirely, there's gaskets.
Add in my exterior mods (1-2K depending on if you can find used Bix)...
And then 2 grand on suspension + 1K on AMG brakes.
6-8+ grand to look almost stock, but drive like a racecar. and you have a very modified car that looks very stock....but not. There's just something people can't put their finger on. ha. The idea being the cops won't notice me.
Well, I got pulled over once at WOT and the guy commented on the noise.
A recent dyno by a fellow coupe owner with similar mods to mine, pulley, SS header and auto yielded I think about 195 at the wheels which if you add the loses from drivetrain and auto would be right in the ball park of 240.
But he failed to put the car in dyno mode, so might have been even higher.
I now live close to a place with a dyno, just don't want to part with the cash.
And I'm guessing I'd need to spend a little time doublechecking for pressure leaks on the intake.
Here's a pic with 17x 8.5" in the rear. I just missed out on some 15mm spacers on the forum. Would accomplish the same look, but yes, the wider tires in the rear make for better cornering.
