Have just bought a 4 point rear cage, so in the deciding what to do phase. Seats will be ripped out in next week or 2 (Just got a 13 month MOT
and will get mounting plates welded in, even if its £150. Safe than sorry n all that.
What's a point of a roll cage, if you ever need it, punctures through the base of the car, or just becomes completely unstable
Get plates welded in
NB: Anyon know a decent welder around the Brighton Hove coast- ive got a couple places, but yellow pages that's all.
