It will engage a little lower and your peak rpms will be lower. The smaller rollers will load your clutches harder, you may be able to just use rollers and take the tip rivet out to get your rpms back on top. The pink rate spring will lower your engagement more and make it nice and smooth to ride at low speed their only about $20, you may want to try rollers and remove rivet 1st to see what your peak rpms are, if their low then you would want a higher shift rate on the spring
