So last night i bought the ACT streetlite flywheel with the counterweight from the Gotham racing website. Now my question is was i supposed to tell them what letter of counterweight i needed or did ACT only make one? I know that you can have up to 2 letters difference in rotors, so is it the same with the counterweight and ACT just made "C" weights?

Thanks.

 

You should be ok, ACT makes the flywheel for each model. As long as you have the correct car model/year.

 

There is only one counterweight, you are fine.

 

What would I do without this forum? Thanks guys.

 

Anyone know how much this counterweight weighs?

 

I think the counterweight weighs a tad over 4 lbs, based on weighing the RB aluminum flywheel with and without the counterweight:
