I don't seem to see many 914 circuit racers with 17" wheels on. Everyone seems to stick to 15". Is there a reason for this? I'm less bothered about the looks of 17" vs 15", I'm more interested in this from a performance perspective. Who out there has tried both wheel sizes? what size did you decide on, and why?
I personally have 15" (Cookie cutters 7" wide all around) (IMG:http://www.914world.com/bbs2/uploads_offsite/i31.photobucket.com-3285-1440357310.1.jpg) and 17" (Cup1 7"front 9"back) (IMG:http://www.914world.com/bbs2/uploads_offsite/i31.photobucket.com-3285-1440357310.2.jpg) At the moment, I'm forced to use the 17" on tracks where I need the top speed, due to my low ratio gearbox (a hangup from when it was a rally car). The 17" wheels have a 26" overall diameter. Whereas the 15" wheels are used on slower, twisty tracks. There is a huge weight difference between the wheels (including tyres) of 32kg (70.5lbs) total, which is an obvious benefit to sticking to the 15 "cookie cutters. But weight can't be the only reason why you circuit racers stick with the 15", so what are your reasons? |

I ran Hoosier R35 Canti on Fuch !5 X 8s up front. The wheel & tire assy each weighed in at 32 lbs. The rears were no longer made 10 X 16 wheels with R35 22.5 X 10 Hosier slicks in back... both were bias plys...the weights were the same. The weight savings alone are a very good argument, IMO. At two sets per season even the bias plys were costly.
It's been a while since I looked at the Hoosier catalog but there were a wide array of 15 & 16 inch race tires available.....much more so than 17 & 18 and those were much more pricy. |
