Hrmmm I was told that was correct one. Shit.
Member
Wait I need 5x4.75? I can get those wheels in either pattern so think those wheels are fine?
Member
Vision wheel makes better looking wheels in the correct 5x4.75. They make a 15x8 with a 5.5 back space, which will prolly work for a car with flares but won't work with stock quarters.
summit carries all the wheels. Make sure they are in stock

Okay guys been givin her hell.
Hot lapped like 12 laps the other night and for the most part she took it like a champ.
Only thing is on the way home from the track I noticed a mild vibration at medium load, especially in the 3-5k rpm range. If I let off the gas (no load) , zero vibration. It's gotten a bit worse over the past few days of beating on it. It actually smoothes out if I go past 75% throttle. So it's worst at medium load in the middle of the rpm range. The vibration can be felt in the seat, floor, shifter, steering wheel.
No vibration at any rpm if I free rev.
No vibration upon braking what so ever
I got some mild wheel hop a few passes and didn't let off like I should... thinking I tweaked something. Any ideas on where to start my search?
I was thinking possible the center support bearing ..

Replace the driveline.
I'm coming up with a solution to fix the hop but it's going to take a while.

I began to develop a small vibration on my car as well and it ended up being a very worn rubber section of the csb

It was an 1/8 mile. About the same as the first time but I was a lot more consistent. Problem is I am spinning half way down the track. My buddy with a z4 trapped better than me and makes like 200whp less.
Also this big turbo doesn't really come alive until 3rd gear, and third gear is the only useful gear for me in the 1/8th

Sucka.
Regarding the wheel hop, It's going to be some work and until it's done and has actually eliminated the hop we don't really know.
I have all solid bushings and bearings in the rear except for black (hard) Powerflex subframe bushings which I've shimmed and in the videos you can see they ain't moving. I put the Gopro under the back of the car from multiple angles and the only thing that is moving is the front subframe attach point. The flex at the front is 1/4"-1/2" upward from low rpm brisk clutch release and you can see it flex up during a hard pull. I can't imagine what it looks like during a high RPM launch at the strip and it's probably terrifying to see with big wheel hop. This flex is why people are having the driveshaft kiss the tunnel.
The floor under the back seat is not supported and the box section for the forward subframe attachment that attaches to the floor has to narrow down at the drive shaft to the point that it is not able to control the flex.
The subframe mounting box sections are available for about $250 each. I plan to double them up for a double layer, with lots of rosette welds. Weld in a tube vertically at each attach point to join the box section to the floor. Weld a plate to the floor at the top of the tubes to stiffen the floor. I may make a bolt in truss piece that goes from shock towers to subframe attach points which would be the final 'cluck you' to the issue but I want it removable so that it doesn't ruin my lumber/groceries/airplane parts/dead stiff bodies carrying ability.
To accomplish this, the subframe and gas tank will have to come back out again but I am determined to beat this issue. It's currently laughing at me

Practice practice practice.
if drag racing were easy, everyone would go 9s their first time out.

Yes, it ain't so easy but he should be able to give use a mph so we can guesstimate what his hp is.

93 mph which the calculators are saying is mid 400s lol. That's obviously not the case.
My buddy with a z4 trapped 95 and I pull air craft carriers on him from any kind of roll.
Edit: calculators are saying 93 trap with a 3400lb car is 425 whp lmao.

Well then that means some how I am walking cars now that used to pull on me with my old set up.
It also means I am some how consistently beating cars with 650-700whp , with vids to prove it.
And finally it means that some how I lost 40whp by going from a s256 on pump gas at 14psi to a s366sxe at 21psi on e85.

Ya know what fixes wheel hop?
torque converters

1/8 is too short to estimate power on a traction limited car. Go to the 1/4.
Member
Lmao I'm not ready to go full drag car yet
Cantry Member
The torque converter would lessen the chance of wheel hop but the issue would still be there. PEI330i said that his black car (caged) had no hop and the white car has hop (no cage). Different car but similar issues. Thats what got me investigating deeper into the issue. I'm sure that if I stiffen up the back and put drag radials on it it won't hop anymore. I'm willing to be the guinea pig on this one. I may put some 'kits' together if I have success.
