High Left Side Percentage On A Wisota Mod 4

[Wild Blue 32]

Raceman, How would you fix it? Maybe redo the motor mounts moving the engine right an inch or two? I'm gonna try to make it work the way it is first. Thank you.

[Renegade Cust Susp]

You can get away with high LS% as long as #1 LF corner is heaviest and #2 LF is way heavier than RF. I don't know what a MOD 4 is because they don't run them in this area. But that being said as a big guy I know plenty about high ls%

[RACEMAN]

Wild Blue: RE: Engine offset - Rule M. Engine offset must remain inside frame rails.

If it's dirt, definitely, move it to the right. Talk to all the mod guys. Pretty standard practice.

Also, consider moving the fuel tank high and to the right. This also seems to be pretty common practice.

Bunch of guys here looking out for you.

Good luck.
