I bought this and installed it while replacing my transmission and clutch/pressure plate on my Viggen. I did not want to get the stock flywheel resurfaced, and I didn't want to buy a stock one at $500+. I didn't think this would make much of a difference on a mostly stock car, but I was wrong! The difference was immediately noticeable - the RPMs drop off quicker and it makes me shift quicker. The clutch feel (stock Viggen clutch on a Viggen) is much better than original and this flywheel seems to be a little more forgiving when you slip the clutch a little too much. Overall I am very impressed by this little unit. The weight difference is very noticeable.
