The 6 small bolts are for the counterweight since the stock flywheel has it built in and aftermarket ones don't. It still bolts to the engine with the large nut like stock.

There are however spacers that come for your clutch/PP, at least mine did.

Did you buy this new or used? New it would've come with everything you need including instructions.

Should be a counterweight that bolts to the back of the flywheel. After that it instals like the stock one.Looking at RB site it looks like the counterweight and bolts should have come with it if ypu got it from RB. Otherwise you'll have to get a counterweight from an automatic from the series your car is from.

You need one of these:
They are a counterweight to balance the rotating assembly. This counterweight was cast into the stock flywheel, but with an aftermarket flywheel, you have to bolt on the automatic counterweight.
This counterweight bolts on like the stock flywheel does: you put it on with the 54mm nut in the middle. Your RB flywheel then bolts to this.
It is important to note that you MUST use a counterweight specific to your year of vehicle: IE: S4 counterweight on an S4 engine, etc.

As stated above, if your purchased this flywheel new from Racing beat, they should have included the 6 bolts you need and the counterweight. If you did not receive them, call RB.
If you bought it used, you will need a counterweight from an automatic, and to source some good, grade 8 or grade 10 bolts.
