on my rappy i have the alba pro comp +2 a-arms and i wanted top flip the rims around. looking at it it would give atleat an inch or two more of an extension, so i would have a +3 or +4 extension. i have douglas rims on right now, has anyone else done so yet if so how good is it. want to know before the next flat track race. need all the extesion i can get

 

i have heard its bad to do that and havent done it myself so maybe someone else has had something go wrong with it and if you want to lower it i hear if you flip the rear linkage it will give you an inch or 2 lower

 

Its just the valve stems hit the brake caliper or something. Thats why its bad. You would have to do something with that.
