They make a big difference if you don't have the motor and tranny mounts. If you have the motor and tranny mounts it will not be as noticeable, but still make some difference. Everything adds up. I would do it. It isn't an expensive mod, but has decent benefit.

I didn't notice mush of either while driving.. No noise (ppg dog box owns noise) nore handling.. but the engine did more less at idle (the cams make it shug like a v8)...

I think my aftermarket pitch stop made a difference. Shifting feels more precise now, especially when getting on it. The Kartboy pitch stop is what I ended up buying.
