Pazzo Donating Members 11,132 Member For: 14y 3m 8d Gender: Male Posted 31/05/12 05:15 AM Share Posted 31/05/12 05:15 AM I brought a set of 18s I got of a mate cheap in black,was not a fan of the dodgeeee black paint job. So I decided to strip the paint off and getting them polished, got tyres and threw them back on car, well low and behold on my first drive with them I swore my car accelerated a lot quicker to 100kph. So I came to the conclusion the paint stripping off the wheels saved weight which in turn made wheels lighter, in turn transformed car. Highly recommend doing this if chasing qtr mile times.I am also looking at stripping paint and other odds and ends of car to help it perform better without spending money on a tune to get it to go. 1 Link to comment Share on other sites More sharing options...
STAINLESS again plz You've changed man....

I noticed for few weeks once my avg fuel economy was bout 2km better than usual. Then I noticed I was missing a wheel nut. Replaced wheel nut and economy went to sh*t again.

Try these helpfull pointers. Empty your interior of everything. Even your service manual is adding upto .05% to your fuel use. Inflate your tyres to over 100psi. Takes some balls but equals gains. Polish everything you possibly can. Inside and out. 2 Link to comment Share on other sites More sharing options...

Same theory sort of when coming to surface finish ond air friction. 1 Link to comment Share on other sites More sharing options...
riptide Member 733 Member For: 14y 12d Gender: Male Location: Auckland, New Zealand Posted 31/05/12 05:30 AM Share Posted 31/05/12 05:30 AM So what is the minimum number of wheel nuts I can run?I noticed a good polish really makes a difference too. 1 Link to comment Share on other sites More sharing options...

When wipers are on the way down they seem to be pushing against the air trying to mover over the windscreen and the car slightly drops in speed. then, when the wipers are on their way up the cars speed slightly increases.Maybe if we modify the wipers to rotate instead of move up and down then we can see quite a significant increase in acceleration and better fuel economySlightly off topic here but I think it is useful info if you dont want to get a tune. 5 Link to comment Share on other sites More sharing options...
Worm A much better forum Silver Donating Members 3,808 Member For: 16y 6m 7d Gender: Male Location: Victoria Posted 31/05/12 05:34 AM Share Posted 31/05/12 05:34 AM This is why I am always changing wheels...We run my car in the back physics lab and test for wheel wind resistance... Usually setting the tunnel wind speed to 80km/h...We have noticed the different between dishes and concave wheels... Especially when they are dirty and clean...Surprisingly we found that polished stock 17 inch BF wheels give the least wind resistance and therefore greater take off / acceleration... 4 Link to comment Share on other sites More sharing options...
