'07 M8 suspension and clutching questions?

OK, I ASSUME IT IS TOO STIFF ON THE REAR SUSPENSION LIKE MINE WAS FOR ME (160LBS), SO CHANGE THE REAR SPRINGS TO AC PART NUMBERS 0704-821 AND 822, THESE WILL SOFTEN THE BACK END UP ALOT AND MAKE THE TRAIL RIDING MUCH BETTER. AS FOR CLUTCHING, I AM RUNNING 73G WEIGHTS WITH STOCK SPRING IN PRIMARY, STOCK SPRING IN SECONDARY WITH A 42-36 AC HELIX PART NUMBER 0748-679 WHICH WILL PULL HARDER ON THE TRAIL AND ACCELERATE QUICKER. COULD RUN A SHIFT ASSIST, NOT REALLY NECCESSARY IT WILL SLIGHTLY LOWER YOUR RPM. MAKE SURE TO USE NEW SCREWS IN SECONDARY WHEN YOU PUT IT BACK TOGETHER. I RECOMMEND HARDENED ROLLERS AS WELL, THE STOCK ONES WEAR QUICKLY. MAKE SURE BELT IS TENSIONED CORRECTLY AS THIS PLAYS A BIG ROLE IN PERFORMANCE AND THAT CLUTCHES ARE DEGLAZED SO THEY GRAB THE BELT BETTER. THIS SHOULD HELP GET YOU GOING, MY SLED IS SAME BUT A 162 AND IT WILL OUTCLIMB MOST SLEDS AROUND HERE.
