Drag strip results with 20 in wheels
Ok Guys So Some of you saw my post and pics of the 20s i put on my E55.
I love them and they look awesome. Now the bad part. They ruined my track times. I couldnt believe what a negative affect they had.
To give you quick background. I have a bone stock strong running e55.
I go to the track often. With my stock 18s and the stock conti tires I repeatedly run 12.25 avg runs at just under 116mph. Ive run that time 4 out of 5 runs. every single time ive been to the track
So Now I went to the strip last week with my 20s and figured there was gonna be difference but how much can a wheel really affect a car with 516lbs of torque. Well it affects it alot.
My best run was a 12.55 at 112mph. I had to really squeeze everything i had out of the car for that run. My avg was a 12.65 at 111mph.
That is terrible. I will never ever go to the track with my 20s again. Im so pissed off about it so Im ordering a set of drag radials for my 18s and going back in a couple of weeks and not leaving until i break into the 11s on a stock motor. I may even sell my 20s after what happened.
I should of know better but I was thinking since I had such a big traction issue with my stock wheels and tires. Maybe the wider tires i put on the 20s would help and even out to where i could hit at least the same times with the 20s. I was wrong for sure. I guess even the mighty 55 cant overcome increased rotational mass
Anyone else have similar results

EVERYONE who puts bling over performance has the same problem. No one breaks the laws of physics. Try a super light 18" wheel and pick up a tenth or 2.
