I was thinking about putting the big wheel kit on my zr9 who makes a kit and how mutch is it. Is the main idea to decrease rolling restince.

Thanks

Performance Engineering and Machine makes them...you'll need the offset axle kit which is around 110.00 and then the 8" wheels which are around 100 each for the wear resitant aluminum, they have them at Hi-performance Engineering

I put a set from MOUNTAINE MACHINES of 8" billet green they are sweet with the offset shaft, i delt with Maria she was awsome,, check their web site.

Wahl Brothers also make one as they are listed in there catalogue...Uses 2 8 inch wheels on the outside and the two stock wheels on the inside....

Couldn't resist this one. :beer: Performance Engineering by far has the best-engineered piece. No I don't work for them. Just a very happy customer!

Whats the use of having the 8in on the outside and the stock on the iniside does it increase the radius of the track still or what.

Thanks
Duane

stock ones on the inside just touch the track when it comes off the rails and keeps the track from bending in the middle. the big ones on the outside are doing most of the work.

i have the same performance engineering axle and the quality is amazing!

Is there any clearence issues between the studs and the tunnel with the 8" wheel kit??

Seems to me you'd want all of them to be 8 inchers.
If you use the axle relocation bracket,all of them will be 8's
If you use the offset axle,then you get the little ones on the inside.
From a cost stand point,the offset axle is probably cheaper,cuz you only have to buy two big wheels.
I'm going with the brackets,and two plastic 8's on the inside ,and aluminums on the outside.
