ok, well i still plan to do the test in the next summer.
you know, perhaps the climate/humidity may make a difference.
however i think the meat and potatoes of the test is replicating the set up of the car (e.g. tyres, well maintained etc), replicating the test weight of the car, getting it timed correctly with an accelerometer, doing it on a dry and level track with zero wind and finally perfecting my driving skills to get the most out of the car.
i'm really looking forward to the results. should be a fun day out too.
on an aside i have fitted 4 budget tyres prior to ordering some PS3's next year. interestingly they have a rolling resistance rating of 'C' and a wet grip rating of 'C' also. they are really noisy though
the interesting part is that they are very easy to spin (which makes sense due to the lack of RR). However a customer ordered some PS3s for his Puma so i took the chance to look at the label...they have a rating of 'G'. So i presume that even though the resistance is more it actually aids traction....especially knowing how easy these 'C' rating ones are to spin
