use powerflex corsa ones.

i got some from halfords, they did the job, were twice as strong as the ones i took off and they hold the bumper tight to the back bumper. cos bout £4 IIRC

cause im sure the backbox ways about twice that of a std back box, and the existing rubbers will not be able to take the strain

it may sit straight when stationary but will probably bounce all over the place when moving

Thats strange, mine sits perfect as it is, why else would i need them??

have the exhaust closer to the bumper?
some sit soo low, so need diff rubbers to bring em closer the bumper.

I think thats why?

Yeah i remember someone saying bout focus ones, whats the benefits of having these then?

i believe ford focus ones are shorter and better, if not go down the scrappy and get some. Should be loads there

Been told i need new rubbers for my sebring backbox, where do i get these from and for how much??

Cheers, Jamie
