Someone did not measure when they made the flywheels. The stock S2 flywheel bolts are a touch too long and bottom out inside the crankshaft. The flywheel might seem tight, but if left alone, you will snap your flywheel bolts. We've seen this happen a few times now.
These are the proper bolts to use when using the ClutchMaster F2K Flywheels.

Even when using all correct hardware, we’ve seen many flywheels come loose and sheer bolts. The K24 engines at high rpm will produce some violent harmonics. If you start to feel some additional vibrations and difficulty shifting, STOP right away and check your flywheel bolts. If caught soon enough, you’ll save yourself LOTS of time(and money) in repairs. For this reason, we highly recommend using a steel flywheel for track use.

Clutch Masters Steel K Swap Flywheel designed to work with the adapter plate and a K series engine to S2 transmission. We strongly recommend the steel flywheel over the aluminum on K24's that are spending a lot of time in the higher RPM's. The long stroke of an inline 4 produce some intense harmonics that can result in transmitting those harmonics into your clutch, or even worse, cause loose/broken flywheel bolts. DO NOT USE your S2000 flywheel bolts. They are too long and will bottom out before properly fastening. We sell the correct bolts.
Adapter plate to mate your K series Engine to the stock S2000 Transmission. Includes the alignment dowels for both sides and hardware to bolt adapter plate to the engine. Hardware may vary depending which K series block you are using. Included hardware is tested and setup to work with JDM K24a engines.
RWD K Series Rear Coolant Housing - K24/20z3 RBB style. Also included is a 1-1/4" to 1-1/4" Inch Hose Barb Splice Coupler to extend your upper radiator hose. [You'll need to source a short hose with a 90* bend.]
This is still to date, our preferred method of doing the Kswap into an S2000. This allows you to keep your factory Fuel system (FPR, rail, Injectors), Throttle Body, TPS, MAP, Idle Valve, IAT, and everything fits like factory. The only downside is you do have to do some trimming to fit your intake manifold. [See pics]. Includes: adapter plate, 6 bolts, and NPT 90* coolant fitting.
