Just a quick question as to the RB aluminum flywheel. At the end of the page it suggests to put a scatter shield or blanket, was wondering if that's totally necessary? I'm doing the whole cluth have act and i hate it. I'm getting the exedy oem clutch kit, RB light flywheel, and a counterweight from clutch max. Is this a good mix or should i go all exedy components?

Here's the warning from RB:
Safety Warning
None of the flywheel or clutch components shown in this site should ever be allowed to exceed 10,500 RPM under any condition. This same RPM limit applies to stock components. You must use an engine RPM-limiter to prevent excessive RPM. If your engine is capable of exceeding 8,500 RPM you must install a transmission scatter shield, or ballistic blanket. Failure to implement the above may result in serious injury or even death.

It's just for safety if the flywheel or clutch blows up during high RPM. I find that to be an extremely unlikely event unless you are constantly in the 8 -10k rev range. You would notice issues with your transmission long before a catastrophic failure occurs. It's your decision really.

I do tend to redline quite a bit due to not wanting carbon buildup. I found blankets for as low as $85 from JEGS so it won't cost me an arm and a leg might as well just do it. 12" Width x 45" Length x 2" Wide Straps are the demetions think that would fit around.

Yea then you should definitely go for it. I only redline once or twice a day. Mostly just daily drive.

Not that I'd ever argue against safety, but the components are rated up to 10,500.
Unless you've done major retuning, your engine never reaches this rpm. Keep in mind that the tachometer is 500-700rpm fast at 10k rpm. So when it reads 10k, you're really at 9.4-ish (you can check via an ODB reader).
The other thing is, you probably shouldn't regularly bring your car up to fuel cut rpm, because it puts additional stress on the engine and everything attached to it. You might not have carbon, but you'll wear out ac compressor bearings, idlers, alternator, etc.
So this isn't suuper necessary, but I guess it won't hurt.

And also engine speed has no bearing on carbon build up. You could run at 10k all day for months and still build up carbon. What matters is temperature and pressure resulting from high load (high acceleration). The longer you can keep the throttle on the floor, the longer you're keeping the engine in conditions where it can burn off deposits. Reaching high rpm is an unfortunate side effect of all that.

Nice that's good to know!! I'll hit right at 9.3 then shift never hits 10. Thanks for the input tho veer informative!!

Mistakenly up or down shift into the wrong gear and you can easily exceed that limit.

It is a liability concern for them, and since their products are geared toward racing, they need to be safe rather than sorry.

In a racing application, or hard-driven street application, the scatter shield is a smart move. I didn't run one on my FD, but I didn't run it all that hard either.
