Airborne fear at 170mph
My car is an 07 with the p30 and mods which prob add 100-150 hp. I did a high speed run last week and got 165-170 mph when the car felt very light in the front so I backed off and good thing as I was running out of road , note it takes awhile to slow from that speed. I’ve since ordered a front spoiler which looks acceptable , problem being they are ALL sold for looks not speaking of function, but as I said I like the one I got but it’s not yet installed. Any help or advice on my issue would be appreciated.

I would start with very good new tires. I'm not sure what you have or how old they are, but properly inflated softer tires will be quieter and smoother. I like Michelins, to me cheap tires do not belong on these cars .
Also, check your alignment. That can play a big roll in keeping the car straight. You don't want to be riding on the edges of your tires with crazy camber if your looking for top speed. Thats a typical problem with cars that are lowered. The ABC will keep the car planted if everything else is doing what it should. The car is capable of 200mph stock power and design, given enough room. Good luck be safe.

I'm assuming your tires are not that old. Are you running stock sizes? For high speeds, you're better with higher pressure closer to 40 lbs for less sidewall roll/flex.. The ABC sport will only do so much. Overall it does a great job keeping a heavy car planted. I would really suggest checking your alignment unless it had been done recently with new tires.

Slightly concerning no? As you mentioned the car does take time to slow down from speed, being such a heavy car im shocked it's giving an airborne feeling.
I done 160 mph in a normal non f1 pack sl55 and it felt very planted, no lightness or uneasy feeling inside. Really felt the weight providing stability.
have you checked your suspension arms/bushes?
