Hi, the 19th march I drag race in a ski center. The track is 400 foot long on compact snow, with a sand start. I run on 4-snow's. I just wanted to ask to all you drag specialist if I should swamp my 13t front sprocket with my 15t. Also, should I take off my rear lowering link to get the front lower than the rear? The track is in a hill, thx alot!
