how does the front lowering blocks help with the camber ?

Holy crap 114-120ftlbs?!? how did they derive the number? OEM spec is 83ftlbs. I torqued mine to 95ftlbs. I hope they didn't raise the number just because the bolt is longer...Originally Posted by SUPRAboy80
... i believe it was like 114ft-lbs or 120? Can't remember exactly but it was to what ever they said...
FYI, most M12 grade (black, no outer finish) 12.9x1.25 are limited to around 120ftlbs +/- a few lbs.
I just used the OEM torque spec for these bolts. 120 is too high for them. That might be why they snapped.

It seems like only one bolt broke, otherwise his car would have been on the ground. This may be related to torquing issue.

Definitely very likely related to torque...one bolt might have been over extended. Exact should look into the torque spec.Originally Posted by GSteg

Gsteg thanks for the answer but I am still confused how it will give you more adjustability of camber with coilovers ?Originally Posted by GSteg

I have had inside tire wear with L-tuned springs and dampers I saw that footworks has adjustable upper arms @ carson lexus which I have been considering but would go to coilovers and the lowering blocks if i understood how that will give me camber adjustment
Thanks to anyone who can give me advise on adjusting this camber issue

The reason why it adjust camber with coilovers is because you are supposed to raise the height of the car using the coilovers back to the height it was before you used the RCA. Typical RCA lowers the car by about 1". You then raise your car back up 1". The suspension is now working at a position 1" higher than what it used to be. If you know how a double wishbone suspension works, camber increases as the suspension compresses because it travels in an arc of sorts. The more it compresses the more camber. That is why when you lower the car you induce camber. Anyway, that is the basic idea.Originally Posted by repman

^^^^^correct... Oem spec is 83 lbs for those bolts. The lower castle nut for the LBJ ( between the two bolts) is 119 lbs. Maybe a mix up by Exact in their installation guide????Originally Posted by GSteg

Interesting. That sounds very likely. IF this is the case a lot of people will need to start changing their over torqued bolts out.Originally Posted by PHML

If you check Exact's website, it says to torque bolts to 120 ft/lbs... Hopefully they can clarify this. Good Luck, and happy to hear no one was hurt in this incident

The bolts are grade 12.9, these are the best grade bolts in the market, the torque spec is 120 ft lb. Make sure don't over torque them, you may snap them, but do not under torque also. Make sure torque them evenly, torque both bolts at 75 lb first, then torque them at 120 lb to tighten them. Do not torque one side all the way, then the other!
