Fairly mild WRXs on good tyres are in the low 50s. Theres a few well modified and driven WRXs and a Skyline GTR N1 that run mid to high 48s. A couple have managed high 47s. But there's one WRX which is just totally off the planet and has the record for AWD turbo cars at 44.75. This is a staggering time for a tin top on DOT tyres. To put it into perspective, the over 2L sport sedan (basically unlimited mods, slicks and wings) is 43.31. The over 2L Improved Production record is 45.70, but no-one has broken out of mid 47's in over a decade...

I think Andrew should make a trip up here...
