So did my break in oil change. OEM out, royal purple 5w20 in with a new ford filter. Oil change was simple and filter is really easy to get to for us DIY'ers out there. While I was working at my buddy's dealership, I also decided to put some lighter shoes on. 17.4lb wheels in, 22.5lb ones out!





And one at the gas station!

Same tires ? When I switched to the winters on my car it was 35.5 lbs per tires (new 15 inch) vs 42 lbs weight of the stock wheels and rims.. Do you feel lighter ??

Same tires. I'll be swapping on some focus 16" wheels soon with winter tires also. I figured might as well burn through the oem tires before putting on the tire setup i really would like.

Thanks! and for the record you definitely feel a difference on the car with the lighter wheels. Steering is easier and the car responds to throttle changes a bit better. f

Ya I think to track and AutoX . I will be looking at maybe a set of 16 inch OZ ultraleggra's and some sticky rubber I did like my DZll's I had on my FRS too bad they didn't fit in the size I have so shopping we go in spring ... ;)

White may be a challenge to keep clean, but darn it to heck, your FiST looks sharp. Really good choice with the rim selection as well.
Thanks! I got the last set of those wheels in North America. Had to get sneaky and get one of them imported from over seas hehe

Sadly they're going to be quite rare. TR is the only importer of OZ wheels in the US and they've said they aren't going to import them any more

size and bolt pattern are 4x108 with a 63 mm bore I think . Best I found so far are OZ ultraleggera on tire rack coming in at a listed 17x7 inch wheel at 16 lbs with the right offset and spacing.... rather spendy at around 280$ a wheel.. so temped to drop to the 12 lb 15 inch with a rival 225/45/15 for total weight listed at 32 lbs a wheel though that will mess up my autoX classing and not sure abut sidewall flex in cornering messing up the car setup.. good thing is lots of time till next season for new ideas to pop up :)

I really like the wheels. OZ makes a few nice wheels for the ST.

One note on weight savings of a smaller wheel. Keep in mind the tire will weigh more. I know it sounds silly but it does eat into your cost savings and also check what tires you can find. I'm pretty disappointed with the 205/40 options. Can you fit a 215/35 or 215/40 on a 7" wheel (I'm bad at wheel and tire stuff). There's still savings but I'm just pointing it out. I went down the same path with my M3 putting smaller wheels and the tires were a bit heavier. Still a nice savings tho.

I've fit a 225/45 on a 17, so yes. I've seen a 235 on a 7" but obviously that is far from ideal.

Those of you with aftermarket wheels how much room is there for wider rubber?

I had a 205/50 (winter tire) and a 225/45 summer tires both 17 inch test fit on focus SVT rims (same offset as our factory rims) and they both rub at full turn going slow.. the 205 just rubbed in the front and the 225 rubbed enough to take the paint off the first test drive LOL
could be made to work with a different offset or running a set of spacers. I only test fit on the front and did not try the rear as I saw no point and went and got snow tires that fit the car better and will look into summer tires in a few months as we get closer to Spring up here :)
leaning towards staying with 17 inch as stated before not much over all weight savings going to 16 inch as the tire weight eats up the weight difference between the 16/17 inch rims and I don't like the sideway flex on my winter tire(195/55/15) yes I know its tall and light weight sideways so it leans a lot in cornering .So ill stay with a 40 series for track events and such.. I did find though a 15 inch OZ rim and a BFG rival tire 225/45/15 would shave off 12 lb a wheel over factory rims and lower the car about a 1/2 inch or so ... though that is 2 sizes smaller and will bump you into a different class in AutoX... just sayin
