What I noticed was that the car comes off the corners better with the oneway, with the diff the car really didn't get a good drive off the corner until it was finished turning... while the weigght was transferred to the outside wheels, the diff would just let the inside wheel spin the power away instead of getting a strong drive out of the corner. Corner entry was a lot sharper, not undriveable by any means, but definitely more aggressive...

While I found the car easier to drive consistently with the diff, lap times were better with the oneway... Unfortunately I was having a hard time concentrating today and I found myself making a few more mistakes than I would have with the diff. Still I managed to best my previous best run on this layout in every run today.

This was in stock/17.5 rubber tire class on ozite. Our track allows Paragon tho, for what it's worth.
