hey i just bought a autopower 4 point race roll bar from a local guy its brand new but it didnt come with any instructions you can weld it or bolt it to the chassis dose any one know what kind of bolts are strong enough to use to mount the roll bar

 

u need grade 8 fasteners, thats bolts and nuts!!, the bolts will have 5 dashes on the head, and the nuts will have dots. A local nut and bolt place it best, stay away from large chain stores, bolts may not actually be full grade just knock off's. a local place where i am, is called Bolts Plus, someone there will be able to help u... if ure not sure,, dont do it!! there are paid professionals, that do it for a reason!! good luck

 

i am gona get it installed by a shop but i wana buy the bolts bec i am not sure if they have them do u know what size bolts with ideal for the roll bar

 

Do it right weld it

 

will i be able to remove it later if i sell the car if i weld the bar ?

 

weld in can be removed but costly, bolt in is fine if its occasionally tracked, always check with local track rules and race regulations, if its street only, sure bolt in is fine,
and if the shop has installed roll bars before they will know what bolts u need, once someone sees what they need to do. and determine what size bolts will be used. the bolts will need to be a certain length, and thickness etc...

 

ok great thanks for the help

 

i spoke to my installer and we decided to weld it
i guss ill upload pics soon when i get it installed in the car :-)

 

if you're welding it/modifying it.. make sure that main hoop gets as high to the ceiling as possible..


i never liked how the off-the-shelf autopower bars had the main hoop so low... what good is a roll bar if it allows the roof to cave in 6 inches before it does anything?

 

oh ok thanks for the info ill make sure to tell my installer to mount it as high as he can to the roof
