Nope, sorry this just is not correct. For static vertical load the wheel bearing only cares about where the force is applied which is where ever the tire center of pressure is. So +38 and 20mm spacer is no different than +18mm offset. There may be another component that transfers that load but energy must be conserved.

 

Ya but that doesn't say much. They could actually be using it or they could have put it on there as a joke. You've all seen the failures of bolt on spacers because of the sh*t quality studs used. Theirs must be unobtanium or be swapped out as often as pads are. Hell there was even an evo owner here who's failed at on - the - highway, no racing what so ever. To me, if they really do this, that's like putting 87 octane in the thing. With the cash spent they could have made their own brake hat out of titanium "to fit". OEM trailing arms ...and oem endlinks?....odd.

 

Theres certainly a huge difference using cheap china spacers vs a bolt-on spacer with quality hardware. Ive personally spent time in china and taiwan, I know that quality stuff can be made there but it comes at a price and the type of places asking for parts are beating them down on price so you end up with quality control issues in unpredictable ways.

Theres no reason a quality spacer should fail if the spacer itself is sufficiently thick to transfer load (20mm is totally fine here), the studs used are of known quality (especially not over hardened), and you aren't doing a lug count change.

I would of course rather just have longer studs and run a spacer on the evo, but I wont have issue running a bolt-on spacer on the truck. And I ran a bolt on spacer on the Evo for probably 5 years.

 

A properly fitted and torqued bolt on wheel spacer will not fail. I'm with Dallas on preference of slip ons due to less fasteners to keep tabs on but the reality of it is they're not unsafe, people are just stupid.

I have 1.5" bolt on spacers on my raptor. I run over curbs, jump it, gone through mountain trails at 50mph, towed my car across the country. Never an issue whatsoever in the past year they've been on the truck. Yet in the raptor community there's people who have lost wheels doing 30mph driving around town. And when you ask them if they torqued them with a torque wrench and if the tip of the stock studs clears the back of the wheel, there's never a response.

 

AYOUSTIN,

You guys seem to know a lot about spacers. I'm on the stock Evo X GSR wheels and I'm looking for a more aggressive look. I want to get some 20mm spacers. If I were to get 20mm spacers AND lowering springs (1.25 inches in the front, 1 inch in the back), do you think I would need to roll my fenders? ANY help you can provide would be appreciated.

Not really sure. I've never owned an evo x but they can fit some pretty wide stuff compared to the 8/9. Might be worth it to check one of the fitment threads to find a better answer.

 

Need to know tire size. With 20mm spacers, the OEM wheels would be +18 offset.

Probably be okay. Way back when, I ran +20 wheels with 265/35/18 DWS tires on non-rolled fenders with no issue.

 

i used JMFab. they are hub centric for enkie wheels. custom size to your needs.

THAT is the ones we're looking for. 67 to 73, not this 67 to 67 stuff. Plus the extra material removed. No wonder it's the most expensive of the bunch.

 

Those prices are definitely cheap, I cant even justify making spacers at that price. It'd end up being like $25/hr considering setup for 1 off part, time to adjust the model for thickness, ID, and OD, and post inspection.

Lathe would make things much quicker but its a 100k machine for Y axis milling.

 

i run slip on spacers. without the center hub thingie. but im a fool

 

RAZORLAB,

I am running the Michelin Pilot Sport 4S on the stock wheels. The tire size is 245 / 40ZR18 (97Y) XL. Do you think I would have an issue? I know NOTHING about wheels, tires, and offsets. lol

 

99% sure you won't rub the fenders with that setup. However, those tires are a bit tall and you might rub the front fender well plastic liners on tight turns.

 

curious if you still have the rotors for sale, if so pm me please thanks!
