i want to put a gsr strut bar on my LS, what kind of bolts do i use? and i read somewhere that there is a reinforcement plate under it or something?

 

You need big washers to spread the load.

GS-R Front Brace on LS
From: CAPSULIER@aol.com
Just added a front strut brace on my 1995 Integra LS. There are holes plugged with rubber stoppers where the brace goes in the higher models, GSR and SE. Looking at the Service manual it appears that the bolts/studs are welded into the body at those spots. I used 8mm stainless bolts, with flat washers on both sides and self locking nuts. The fasteners are not available from the dealer, I got them from a bolt/nut supplier. The flat washers I could get are just barely bigger than the 13mm bolt head. Question, how much stress would those bolts transfer to the sheet metal in normal driving over average rough roads? Are larger washers really needed to spread out the stress over a larger surface area? I am planning to keep the car for a long while. All engineering types out there what's your opinion? How about some theoretical stress analysis?

The car seem to handle significantly better with the brace in. The steering seem to be more neutral and the car seems to take corners with less bodyroll. It also seems to be somewhat quiter too!! The body roll and quiet part just may be my imagination. A worthwhile project for a total of about $70.00 with everything and 30 minutes of elbow grease. The strut bar is OEM got it mail order.

thanks
so i use wider AND thicker washers?

 

go to Brofasco or other fastner/screw company get some high grade nuts (or even home depot)

large washers, good quality never hurts
