When i saw that it was 20+ grand i thought it was expensive but if one were to buy the parts separately plus labor one would likely pay the same so my question is what benefit is there to having this kit compared to Katech or other companies who Include forged internals in their kits. MTI says the kit is safe on stock internals but do they mean for normal driving only? what about the occasional trip to the track or street races? hard launching and such..
