Yeh i would agree with that i think he holds a place in history of the TR7 as he continue to evolve the Car after Triumph stopped building it
Also as Chris says no other company has carried out so many conversions in such a short period and made them quite so distinctive.
His reputation at the time and since has made the car folklore in some respects.
S+S however like to keep the car close to an original 8 and certanly have a well respected name throughout the TR7 community infact without the likes of them and Robsport perhaps the TR7 movement wouildn't be as strong as it is.
They are truly the legends
As Grinnal are now no longer interested in his creations.
Special is ways that they obviously handled much better than the standard TR8 better brakes, stregthening and power output as they continued conversions into the 90's
Most Tr7's will turn heads now but a well carried out Grinnall conversion will have kids drooling in the streets as they have a much meaner stance [:D]
