Great Product
First off, the staff at Grimspeed were very helpful in getting some specific measurements on the product to be sure it was what I wanted. The shift knob itself is a well made product with excellent finishing. I was a little concerned that it may be too smooth or slippery, but the texture is just right! Only time will tell as to how it holds up, but I don't expect any surprises as delrin is a pretty impressive material. Also, the Stubby shift knobs fit the GR Corolla, as that's what I bought it for.
