Could anyone with cusco coilovers please tell me the size of the rear shock mount hole. specifically if its the same size as an m12 bolt. I have jic's and want to switch over to the cusco rubber mounts because I just can't take the noise of pillowballs anymore. The size of the hole I would need would be the same size of an m12 bolt(the ones that typically have a 17mm nut on them). stock shock nut size is 14mm my jic is 17mm, so if cusco is 17 i am guessing it will work.

 

Lols... Im doing the same thing for the rears... Im waiting for the rear upper mounts from Z1... I ordered them early December so I should be getting them soon...

To answer your question... An M12 bold will fit with room to spare... I upgraded all four bolts in the rear with M12 10.9 grade bolts an nylock nuts...

 

I wasn't talking about changing the mounting bolts to the chassis of the car. But thank you for the information. I also noticed tein uses rubber rear mounts I wonder if they will work. by the way how much were the rear rubber mounts.

 

Under $200 shipped for rear hard rubber mounts... If you want a more accurate amount please feel free to contact Z1 Performance...

 

You will not be able to convince Tein to sell you parts unless you can prove you own their coilover's and are in legit need of the parts. They aren't after part's business that doesn't support their end users. Other then that little policy, they have alway's been very nice people to talk to on the phone.

 

Try using the stock mounts... I have thought about it but just havent had the time to see if it actually works...
