what do you like about it.

 

most shops wont lighten your stock flywheel. they will resurface it but nothing like a light weight flywheel. reasons being its dangerous since the flywheel may not hold up to the abuse and could crack or shatter.

 

most shops should lighten your stock flywheel, well at least up here in the northeast they do. Its very common up here since alot of racing requires a stock type flywheel. If you can find a shop that will do it, its your best bet.
Now for some info...
SWitching to a lightweight flywheel or machining out the back of the stock one and making it lighter is the equivilant of taking some 100- 200hundred pounds off the car. (sorry cant remember the formula) Rotation weight, wheels, tires, driveshafts, flywheels etc cant really build momentum like the car can as a whole, so whenever you accelerate it has to fight that weight much more than say the weight of teh vehicle. So what im saying is that if your serious about losing weight start with the drivetrain, it is the most important place to lose weight.
A lightweight flywheel feels slower to some people. Since the engine has less inertia it drops revs quicker in between shifts so if you run a lightweight flywheel on a stock clutch it wont hit as hard. I put a 35 pound flywheel in my friends 4 cyl toy pickup and it was so slow but it would knock your teeth out when he shifted, it felt fast but wasnt.
On a light car like the xa/xb a good hard hitting clutch and a lightweight flywheel should make quite a differance in performance. Findanza is a great company and i personaly trust their products, lighteneing teh stock one is always a great option as well depending on price. As for a clutch ive never shopped for clutches for these vehicles but it usualy comes down to how you drive it. Organic clutches are smoother and dont hit as hard and kevlar clutches handle high heat much better, or ceramic if your looking to knock out your teeth. Just make sure its a "sprung" clutch or it will be very hard to daily drive.

 

i took a 22 pound toy pickup flywheel down to 10 pounds and burned up 2 centerforce dual friction clutches behind 400hp and never had any problems. Its solid steel, it should hold up even better than an aftermarket aluminum one.

 

^ i like your words but im not understanding why you are saying you should shave down your stock flywheel .... im not sure how you are getting a performance gain that can be noticed this way ...and you are also making a part weaker like this.

 

I take back my above post ..but I dont know how it would hold up. Just for peace of mind Ide rather get the light weight one. Any time I hear of someone shaving something down its normally never good. But then again .... im no expert on the subject so if other people are doing this speak up because ide like to know more info on it eventhough my light weight wheel is on its way.

 

theres nothing there to break. have you ever seen a flexplate for an auto? talking 10mm thick whereas the flywheels are well over an inch thick. A flywheel is like a brake rotor, its like saying slotted rotors will cause your wheel to fall off.

 

but thinning it out - would you be more prone to it shattering? i dunno ...maybe im just talking foolish right now. but ide like how your replying.

 

no it wont shatter its solid steel. Flexplates (the flywheel for an auto) is soooo much thinner.
