Will the stock TPMS work with Enkei Kojins or will I need to buy aftermarket?
 

As the title suggests, I'm wondering if the stock TPMS will be alright in the Enkei Kojins. I'm planning on picking up two 18x8.5 +45 front and two 18x9.5 +45 rear.

Yes.
Don't do staggered unless you like understeer.

Yes they'll be fine. The car is designed for a square setup. Staggered and you'll need to start screwing around with the suspension to get it to handle properly. Best to go squared. If you just want the look then that's a different story.

The TPMS will swap right over to the new wheels just fine.

I currently have a staggered setup (mainly because I love the look) and did not notice too much difference when autoxing compared to the stock ones (our courses are pretty low speed though).

I'm not sure how much difference staggered vs square makes, unless you're driving at the limit all the time.

Even when I was pushing my car 8/10 on 17x9 square and the person behind me was on staggered 18s, he was hanging right with me - he didn't seem to have any negative handling effects. Shrug.

Clipdat: there are two ways approaching limit. Pushing more, or reducing limit. Imho in wet or in winter extra understeer might get way more noticeable, even in never pushed daily driven only car. And if this car was bought/chosen for good handling, it might be a bit unwise to make it worse even if practicality bits like, eg. ability to even out wear with rotation or simpler to get replacements for damaged single tire/wheel or easier to find buyers for square set if selling in future, doesn't matter.

TBH, unless suspension, tires and drivers are same, can always setup the stagger wheels to perform "almost" close to stock setup.

back to TPMS, yes you can use stock TPMS to Kojin wheels.

ichitaka05: but if many wishes reduce understeer vs that of stock, then going staggered/other way, reduces available adjustment ranges, how much one can do that, or require extra parts/spendings. For example, not just cheap camberbolts, but also camberplates, rollbars, non-stock springs/dampers and so on .. imho better not do mistake in first place, then spending even more to fix it.

I don't drive aggressively enough to get my car to understeer with my 225 245 stagger. And lately, I have been trying. I had 4 different square set-up before going staggered. It's really not that different.

car handling aside, you would be limited in rotating your tires in doing side to side vs rotating between all 4 corners.

Well, if you get full custom (or at least close to) coilovers, cambolts, LCA & Toe Rods, you can fix th understeer caused by staggered wheel setup (to certain level)... BUT! Would I recommend it? No, I wouldn’t. Most of the owners who staggers are 1. Like the look of the stagger, 2. Boosted & don’t wanna run wide Tires to rub at full lock, or 3. Suspension expert that know what he/she’s doing. 90% of owner prob fit in first 2.

In the end, it’s his car, so do whatever he want to do w his car. We all can give advice and that’s all we can do.
