The rear out arches on my s2 have gone so ive got the rapair panels to do them but how do i check if the inners are gone to? cheers

 

when you cut the outers out, you'll soon see.

 

ok is the inners a big job? cheers mate

 

I replaced inner and outer rear arches on my s2
the inners are easy and well worth replacing if you got the outers off.
Be carefull welding the outers on not to put to much heat into the rear 1/4 panels
and distort them.
