longsh07 Posted January 30, 2016 Share Posted January 30, 2016 Just found this on Youtube which I thought was worth a watch. They compare a not quite stock 18x8.5 ET30's (225/45 Front, 245/45 Rear) vs a 19x8.5 245/35 Front / 19x9.5 275/35 Rear ET22 setup on a 35h Anniversary 350Z around Tsukuba. For those just interesting the results the 19" were slightly faster but they said the tyres were more unstable than the 18". Actual lap time difference was 0.3 seconds but they said that your average driver might be slower on the 19". They also asked the question if the cost increase is worth it for 0.3 seconds. Skip to 7:20 for the actual comparison on the 350. http://youtu.be/o6Glkf4jwkM Something to think about before you buy your wheels (unless its just for looks) Quote Link to comment Share on other sites More sharing options...
Ebized Posted January 30, 2016 Share Posted January 30, 2016 I think you will find anyone who has seriously tracked their 350's would use 18" - Zmanalex is a case in point. Quote Link to comment Share on other sites More sharing options...

For one, track tyres are limited sizes in 19". Much more flexibility in the 18s. Quote Link to comment Share on other sites More sharing options...
Payco Posted January 30, 2016 Share Posted January 30, 2016 19's for show 18's for go. 3 Quote Link to comment Share on other sites More sharing options...
roadtrip Posted January 30, 2016 Share Posted January 30, 2016 Very interesting, especially as they're using the most common tyre sizes. Great comparison as well, I thought the difference would have been more significant, I imagine if the 19" combo were cheap heavy wheels and tyres then it would have been. 1 Quote Link to comment Share on other sites More sharing options...
Jay Kay Posted January 31, 2016 Share Posted January 31, 2016 In the real world, I can't see many people noticing any difference. The amount of times you here about people fitting air filters or an exhaust then stating how much the pick up has increased etc. having spent the cash they talk themselves into imagining a gain that in all honesty, probably doesn't exist Quote Link to comment Share on other sites More sharing options...
docwra Posted February 1, 2016 Share Posted February 1, 2016 I ran 18s on the front and 19s on the back of mine, best of both worlds 1 Quote Link to comment Share on other sites More sharing options...
