fitting 17"radars onto a red9 beam do i need to tub my bus

[68bayman]

hi everyone
i need to know if ive got to tub the inner part of the door if im fitting 17"wheels onto my red9 beam and lowering it onto the last but one hole on the beam, im asking this question to see if its worth the hassle before i buy the 17s or just stick to the 15s
are there any members who have done this to there bus , i know i will have to tub under the seat im just unsure how far across and roughly how much higher ive got to go
thanks

It will depend on the profile of the tyres! i have fitted 18" wheels on a splitty with a red 9 beam and standard tubs so im thinking 17" no probs unless your going silly low if still unsure i would ring simon @ red9 he is usually very helpful
