I have a set of Kosei K1s 17x7.5 114.3x5 +45 offset from my 1G DSM.

Is this offset going to be too much to run on an Evo8?

Searched, but couldn't find anything specific to the offset on this wheel on Evos..

Thanks in advance!

 

Seems a bit narrow and higher offset than normal. Larger the offset, closer the wheel gets to the brakes. Most of the 17's we have are no narrower than 8" and have at least a 40mm offset. Seems a 45 with that width might hit the brakes. Sounds more like a Honda fitment.

 

I thought larger (positive) offset made it further from the brakes?

nope. you're backwards. lower offset= inner edge of wheel rim farther from hub surface.
going 1/2" narrower than stock, PLUS the spacers you'll almost definitely need to clear the Evo brakes (at least in front, possibly rear as well) make these a very illogical idea. Scrap the idea and get some more appropriate wheels IMO.

 

figured as much. just figured it was worth a shot since I still had them.

 

If I were to get spacers, what size would be appropriate? I realize they are a bit narrower than stock... but I have them since they came off my DSM, and they're really nice wheels with brand new tires... this would let me make my stockers into winter wheels.

 

It would make much more sense to use the narrower Kosei wheels you speak of as your winter wheels, as a narrower tire works better in the snow/rain than a wider one, and a wider tire works better in the dry.

That being said, if you absolutely must use these wheels, I would guess you'd need a 10mm spacer to be safe.
This eliminates the option of safely just throwing a spacer on the stock studs as it will reduce the amount of threads holding your wheels on.
That is not safe, so this necessitates buying longer studs.
Longer studs necessitate open ended lugnuts if you don't run the spacers all the time. Given the cost of spacers and longer studs, this is one of the many reasons I am trying to tell you to just sell these wheels and get something appropriate instead of "reinventing the wheel" (literally) just to use some wheels that were under $200 each to begin with.

 

yeah, totally hear ya. I didn't even think about the studs/lugs

I would love to sell these off to someone who has a DSM/Subie/5-lug Honda/Lexus/RX-8... whatever, but I haven't been able to thus far. The main reason for wanting to keep them is the fact that they have $600 of almost-new tires!

Definitely going to try and sell 'em, thanks

 

put 5-10mm spacer and you should be good

 

"Good" along with the whole studs and lugs issue we already hashed out
