I agree, up to a point.....reducing unsprung weight will also benefit the performance of the suspension over rough and uneven surfaces, however, Tsukuba (I'm sure..) is a glassy, babys bum smooth circuit and the drop in gyroscopic rigidity as a consequence of a few less kg's/wheel would hardly result in an improved steering response to the point where it would come close to acheiving the same benefit (in terms of reduced lap time)as a drop of 60kg in sprung weight.

She yabbers a fair bit too, you've gotta take that into account....

This will all be highly amusing and interesting to the cop who's booking you for speeding... claiming that your wheels are a kilo lighter than stock and therefore you can get down the road quicker will surely convince him

 

No no no pepe, you have me all misconstrued.....these wheels are for track use only!!!

 

???????????? Why track use only

 

'Cos, Taka, round here we never race on the road, do we.......?!

 

for 9k they had better be magnesium

 

OH YES...

I am sure it is a educated guess not a lucky guess ~_~
