on my 92 civic hatch i got the after market adjustable coilovers on it and lower controls are but where the rear lower contol arms meet the coilover what size bolt should i use i have heard grade 8 but i need help with this like sizes let me know what you got thanks

 

As in MM? 12's

 

grade 8 minimum. 10.9 is factory rating.

12mmx1.25pitchx70mm

 

i would honestly get them honda..i believe they are like $3 a piece...i know theyre not exactly cheap, but it is your suspension were talking about

 

i cant get them from ho nda being i need the a little longer to put a nut and bolt on the other isde

 

You can get grade 10.9 bolts from hardware stores and they are stronger than the bolts on your car now. I've done 3 cars complete suspension rebuilds and autocrossed all three and NEVER had one problem.

and they are actually $6.09+tax each from honda

you still want that spoiler

naw a lil too far away and a lil too much for my budget

 

bump

 

To be honest. I'd get the Honda bolts.

Honda redesigned them to prevent future siezing.

 

And just to clarify Grade 8 is not as strong as 10.9, that would be Grade 5. 12.9 is equivalent to grade 8. Just sayin.
