I ordered some springs from langston racing this past week and I was going to try stiffer springs than what I needed cause I really hate bottoming. I like to slam into things or just jump into stuff. Anyways, they called me and said they didn't have that size so I had to go with the size down which is ok for my weight. The person on the phone said to compensate, just use a heavier oil...7.5wt. Does this work? Never heard of you guys talk about that before.
