ok I was skeptical of the overall value of the work involved in cleaning and grinding my tires....
tested 1200 Hoosiers and SD-44 ARs after a night of racing....they punched 40-44 and 44-48 respectively..
mixed simple green and water, as per recommendations found after searching here...scrubbed the heck out of each tire...rinsed... let dry in sun...they looked like brand new and felt different already..not necessarily softer..but tackier..
took 80 grit metal grinding disc on 7" variable speed angle grinder..just touched the treads..enough to pull up rubber dust, but not enough to smoke hard...
let tires cool in shop...punched...the 1200s punched 36-38 and the ARs punched 40-42..on average 4 durometer points!!! and they just felt stickier too..and didn't lose any tread depth in the process!
so, to any skeptics out there...the 2-3 hours of work it took to do a total of 6 tires was definitely worth it..we will see how much it really makes a difference during qualifying and the show this week!!
Thanks to all who help here and post such a plethora of valuable information..it is truly making my two man, low budget operation slowly turn into a real race operation that can hang with the mid to front of the pack..now I just need the seat time to make more consistent laps to get me there!
