the 27" will fit fine with the lift kit you already have. you want have any problems with rubbing, maybe if riding two people. the 400 has shorter shocks and a softer ride than the 450. alot of riders don't keep the 14" rims very long, they ride ruff and not very many tires to choose from. There are alot of 12" rims to choose from and a big choice of tires to pick from.

the wife is running 10" and 12" zilla's on her 400 foreman with just a lift kit. But on the front drive train, she is running 450 suspension on it now. she only has a snorkel and clutch kit and it pulls them very well. Sorry I forgot that I had to do alittle trimming on the rear plastic with the 8" wide aftermarket rims.

scroll down alittle, there are some pix's of it here.

her bike has complete 450 (shocks, a-arms, knuckels and axles) the 450 a-arms/axles are 2" longer and the shocks are like 3" longer than the 400's. so this gives more travel up and down. she does not have a lift on the front, just the rear. The 400 frame is 1" shorter in height than the 450 frame, so this is another 1" added to the 450 shocks on the front of her 400 foreman. This is why no lift is need on the front.
