I have a 89 Crx Si with skunk2 full coilovers and a couple cheap upper strutbars. My chassis still is not as stiff as i would like it to be. what are the most recommended stiffening upgrade to make it perform better. This is my track car fully gutted to 1800 pounds. No Ac No dash No speedo. Not my daily driver. My Full roll cage is in the process but if i add lower arm bars is that going to make a difference?
