Tell me if I'm wrong

At first thought, I would have said that stud replacement spacers are far stronger and durable than the bolt on type. But reading the above, the way you put it, I want to change my opinion on the situation.

I was sold on only doing this using the stud replacement type spacer but now that I read it this way, it looks like the bolt on might be the better choice.

Which is the better choice from a durability standpoint and not just an "easy install" point of view?

Seems to me that the fewer mechanical connections holding the wheel to the hub the better, but now I'm second-guessing that idea.

I tend to break things that I drive and I don't want my wheels to be the weak link.

I do not plan on ever tracking my car. What is the difference? Are the replacement studs stronger and able to take more force for track use?

Just safer since in a track the last thing you want to happen is for one of those adapters to come loose, And mind you it's a safety precaution since I've not heard of any issues with ver 2 which is to say there isn't any.

Any pictures of 15mm in the front and 20mm in the rear?

DIY: ** Rear 20mm stud replacement spacers

I looked up the Ichiba spacers on their website and found that the Version 1s are slightly cheaper than the Version 2s. Hell...it might take more work, but you're saving money.

Can anyone tell me what minimum length studs will accommodate 25mm spacers?

fuct · 10-24-2011, 08:57 AM

i read you need to be able to turn the lug nut a minimum of 7 complete turns. if you cant get 7 your studs are too short.

Thanks for the advice Fuct but I really was hoping for an exact measurement like 60 mm. or something.

I'm looking to add 5mm spacers up front and 15mm DRM rear. I'm thinking I should be able to simply add a 5mm spacer up front without any additional hardware. I would probably get 2 less turns of the lug nut. Think I'll be fine? Anyone know of any brands of 5mm hubcentric spacers without extended studs out there?

Might have to just buy H&R DRS style and not use the extended studs...

Does anyone know if i can put the bolt-on spacers up front if i get 20~25 MM spacers? would 25 be too much up front? i'm gonna get swifts in spring. I want to do 20F 25Rs with the sp Rays, but i dont wanna change studs lol

Imperial · 11-04-2011, 08:12 PM

Yes... But I think 25 mm would be too far out. I'm running 20 and already it scrapes the inner fender liner on certain bumps.

Ages · 11-04-2011, 08:26 PM

So with 20s I need stud replacements ? And thx for the reply.

Imperial · 11-04-2011, 08:32 PM

I'm using bolt-ons. 20 mm will clear the OEM studs.

Ages · 11-04-2011, 08:33 PM

Awesome, thank you good sir!

Ages · 11-04-2011, 08:35 PM

Also.. Sorry.. What brand are you running with?
