Default 4.10s or 4.30s

M6 car

Right now its btw

4.10s wit a 27" slick

Or

4.30s with a 28"

Which will work best at the track? I don't want a big tire eating up power down the track.

I've been using the gears calculator and both of these combos will let me trap 125 with a 6500 redline.

Which will ultimately be better?

Need to decide so I can order my rear tomorrw. S60

GRENADED my 10 bolt today.

I'm assuming this is for the car in your sig correct. If so I would do 4.30's. Looks like you have a some good power to roll the 28's down the track.

Just to throw it out there, I am running a 28x11.5 tire with 4.33's on my setup

I'm running a setup similar to yours and I went with 4.11s. I chose them because I wanted to stick to 27" tires so I dont have to mess with my wheel wells to clear 28s (plus I think the 28s look too big).

I hear the 28s hook alot better, so we will see how i do with 26s and 27s.

I went with a 9" rear, so if it comes to it I can always swap the gears out without too much trouble.

from this thread: https://ls1tech.com/forums/wheels-ti...ag-lights.html

A 26 inch with a section/tread width of 10-10.5 tire requires no cutting, bashing or otherwise abuse and mutalition of your bumper or fenderwells.
A 27 inch tire should be safe as well, but carefull attention will have to be paid if the section width is 11.5 or greater.
A 28 inch tire will require the rear bumper be trimmed, and depending ont he section and tread width, you will have to hammer the fenderwells (facing you as you look into the wheel well on the left and right sides)

s60 en route with 4.30's.

Thinking about running the 295/55/R15 MT ET Street Radial. It's 27.8 tall and will be perfect for the gearing and MPH I need.

Anyone running a similar tire with an M6 and getting it to hook?
