Default Does having my car slammed/lowered hurt performance?

Hi guys, as the title states. Does lowering your car a lot hurt it's performance? Mainly as in does it affect acceleration? I had a friend tell me that my car would probably be faster if I raised it a bit since at the moment im tucking front and rear. What do you guys think? Is he right or does height only mainly affect handling and comfort?

He doesn't have any, he just likes cars lol. He's not the only one who's told me that either though. I've been to the Street races (only once though, please dont lecture me. I was curious lol) And the guys there also told me the same thing that If I wasn't so low, the car would have more traction or something like that.

What kind of power is your car making?

Not much, all I have is intake and cat back exhaust. It's an 06 IS350. So maybe 316hp crank?

^^I wouldn't worry about it then maybe an alignment with better tire options. Raising your car won't do anything.

Acceleration, no; traction off the line, perhaps...minimally. The key is on RWD vehicles you want the rear to swat a bit off the line to transfer its weight onto the rear tires. If you're slammed or on STIFF springs or have your rear dampers set to MAX stiffness, you'll not hook and more than likely spin a bit. Of course tires, tire pressure, road conditions all factor into this as well.

Measure your fender-to-ground clearance (upper-most part of the fender [middle] to the ground). What is the measurement? I was at 24.5" with the factory 18s and am now at 25.5" with 19s.

Yeah my car is tucking all around so I'm pretty low. And my BC coils are set to one notch away from max all around as well. It also doesn't help that my car is running stretched tires either I'd imagine... I'm running a 235/35/19 with 19x9.5 wheels on the back. The front is also tucked and running a smaller 19x8.5 wheel with 225/35/19 tires. I'm sure with better and wider tires my grip would improve for sure but for now I was just wondering how much height plays into this.

Also what part of the fender exactly are you speaking of? I don't quite understand

^Measure from the upper-most part of the arch of each fender to the ground. Just curious how low you are.

So your saying being lower reduces my cars performance off the line? My car is also set to full on stiff basically as well on my bc coilovers with the standard spring rates.
