Looking for some shorter slicks so I can go through traps at top of 4th gear. Preferably a 20/8/14 or 21/8/14. Can also use a 15" rim, which I have readily available but less preferable.

Trans info:

Final drive: 4.12
1st: 3.5
2nd: 1.95
3rd: 1.42
4th: 1.026

Shift point will be around 8k rpm.

I can change 3rd/4th (have to change in pairs) to 1.36/1.03 or 1.36/.97 but we suffer from a tall 3rd gear as it is.

This is in a Neon btw. N/A. Think I'll go through traps around 112 mph or so. Figured you Honda guys may know where to find smaller slicks.

I can't seem to find any on M&H, Hoosier, or MT's websites.

 

hoosier makes sum but not sure if they make them for 14" i know they do for 13"

 

Looked at Hoosier, Phoenix, MH, Toyo and MT and none show smaller than a 22". MT used to make a 20x6.5, and i think a 20x8, but are not listed any more.

 

You need a shorter final drive. Look into available FD's before buying that small of a tire. Something around a 4.5fd on a 22" slick would be perfect.

 

This is the shortest FD available. Generally it's only 3.55 and 3.94 for Neons. The 4.12 is an export only FD and very hard to come by. Without having something custom made by who knows where, this is what I'm stuck with. I ran the 3.94 last year trapping 101, and with the 24" slicks I ran, I was running through at very top of 3rd gear. New setup this year, and I figure I can trap around 110 or so. Going with a taller tire on the 3.94 would be a step backwards, and it wouldn't fit. The slicks rubbed as it is last year.

8k is about as high as I need to be revving with the long stroke too, maybe up to 8500 with the forged bottom end that's going in.
