in addition to the camshaft from a golf gti mk2 I also ran my car partly stripped out with no sound deadening and only the 2 front seats. the weight loss had a bigger effect on perfomance than the camshaft did! it wasn't just improvements in acceleration, it would stop on a dime and went round corners like a legend! i've just strippedout my new 16v in the same way for the same reasons and it's had the same effect! only it's faster!!
