.5" really worth it - Toyota Yaris Forums

mastaofdisasta · 05-04-2009, 02:19 PM

Ill make it quick

Rota slipstream 15x7 - 12.9 lbs

Rota slipstream 15x6.5 -11.9

rota attack 15x6.5- 10lbs

Is the extra .5 inch really worth 4 lbs of unsprung weight?

what would yall go with.

And btw im goin with df210 drop

*kimona* · 05-04-2009, 02:29 PM

IMHO, far too much hoopla about a few pounds of unspring weight on this forum.

You're going to drop the car on DF210's. What wheel offset and tyre size are you considering?

BLAZINBLUEVITZ · 05-04-2009, 02:31 PM

15X5 35MM OFFSET

mastaofdisasta · 05-04-2009, 02:33 PM

15x6.5 40ish offset.... what do u mean with all caps Blaze?? What tire size is recomended? Im so worried im gonna waste money and messs up my setup. I just want to get it right the first time ><

SOOOOO 15x6.5 df210 wnt work blaze? ur confus.

i read somewhere that 1 lbs. of unsprung weight removed from the wheel is equatable to 10 lbs. static weight. so 1 lb. dropped from all wheels would be 40 lbs. removed. I don't think this is very 'scientific' but it is something I ran across from a website; don't take my word for it.

keys to remember are, the wider the tire: more rolling resistance due to more rubber on the road/but better handling in turns due to more grip
the larger the rim in diam.+weight: the more rotational force exists-- easier it is to continue going in a straight line/but harder it is for the tire to change directions.
grab a bicycle and spin the front tire in the air, then turn the handles and see what I mean.
as for rim width, I don't think 6.5 and 7 are much of a difference except extra weight and tire selections...possibly less tire roll, but I doubt that

BLAZINBLUEVITZ · 05-04-2009, 02:44 PM

no i have those scion wheels which are 15x5 with a 35mm offset i think and i want to put 205/55/15's on them. i was just hijacking your thread.....

*kimona* · 05-04-2009, 02:54 PM

15x6.5, ET40, 205/50/15 w/DF210's.

scape · 05-04-2009, 03:00 PM

np, just some insight I thought about myself-- looking to get new rims too :)
the slipstreams at 6.5 wide are 13 lbs. on some websites...maybe this is a misprint, just wanted to let you know.
I keep going back to wanting buddy club p1 qf, expensive though!

mastaofdisasta · 05-04-2009, 03:21 PM

no 205's? WHY

HTM Yaris · 05-04-2009, 05:41 PM

Actually ,it will be only 2 lbs of unsprung weight ,since the Yaris only has 2 wheels connected to the drivetrain . The other two wheels would be static weight .

Loren · 05-04-2009, 05:45 PM

Don't confuse unsprung weight with rotational inertia. Anything hanging from the suspension when the car is raised is unsprung weight.
