The general consensus is that trimming of the studs may or may not be needed with 15mm adapters, depending on style of wheel.

Have not read of anybody having to trim the studs when using 17mm adapters.

 

right now I am running stock 19" w/pzeros but when I get my MPSS (later in Jan at Costco) I am putting on stock tires (255/35-20 and 295/30-20) onto new 20" Black Powder Coated Cyclones I have sitting in my garage.

 

watson6505,

I can't answer that question yet. I want to make sure that whatever thickness decision is made that Safety is 1st. However, after hopefully looking at more photos, I can make a thickness decision. Thanks.

 

Then the 17mm adapters will be perfect for you. No need to mess with spacers, pockets, or long neck nuts unless you plan to run wider tires on the rear.

 

305 rear tires with 15mm adapters.
255 front tires with 17mm adapters

 

Yes you must if you have 20" Gyrodynes and the 17mm spacers - they hit.

 

Mine had to be ground a little for 17mm spacers with 20” Tornadoes.

 

So looking at Iron Mikes Photos (Thanks for those) the Car looks awesome! I was looking at my F-Type and was thinking maybe 17MM in front and 15MM in rear. I am running 295 in Rear and 255 in Front. 20" Gyrodynes also. I do not have a problem if I have to grind the Studs. Does 295 vs 305 Make Much difference in width to where I could go with 17MM all around? I DO NOT want rubbing and will not alter the Fenders. Thanks

 

what Ive read is that with 305 and 17mm you cannot lower without rubbing. I would advise going with the same size all around, that is what is typically recommended to keep the suspension whole.

Donzi, I think the 15mm or 17mm adapters are equally safe as they will have plenty of stud, not need to change lugs, and they are hub/wheel centric. There is some debate on the 10mm and using the correct lugs and getting the correct torque. Because every tire is different, I would suspect some trial and error to get the 10mm to be perfect, get the right amount of 'turns' for the lug nuts, and the right lug nuts.

If I knew that cyclones and 15mm would not require trimming the studs that would 100% be my first choice. Moving to 17mm and not having to trim would be my second choice. If I have to trim either way, I would go with 15mm just to reduce the amount of debris kicking up to the side of my car slightly with the 2mm less overhang.

Hope this information and posts we are seeing help you make an informed decision.

 

 

I think you would need to paste your wheels, tire size, etc... for anyone to have a chance at knowing if anything else will be needed.

here are pros/cons on the spacer sizes:
10mm spacer: If you ever want to mount a 305 tire on the rear, you can't go with anymore than 10mm. However, to safely mount the wheels, you will need longer studs (a pain to install), or lug nuts with a neck that is 4-5 mm longer than stock. The 10mm will be very apparent.


15mm adapter: The maximum you can safely use with the stock 295 tires to guarantee that there is no tire interference with the fender. It does require grinding 2-4 mm off the end of each stud, but in no way compromises any functionality as the threads don't start until about 6mm down the stud.


17mm adapter: Appears to work with the stock 295 tires, but only under standard conditions. If you accidentally drop a rear wheel off a curb exiting a driveway, the tire could rub or worse, grab the fender and pull it out of shape.

 

You're making the 10mm spacer issue more difficult than it is. You just need to ensure that the lug nut neck fits inside the spacer holes. If not, drill them out so that they do. Those holes should be oversized anyway (which they usually are), as you don't want the threads biting into the aluminum spacers.

 

I'm in for 15s

 

Agreed 100%

 

i have 19 propellors and i really don't understand if 15mm spacers needs to be grinded or not with propellor

 

Based on the information so far ... I would prefer to go with 15MM Front and Rear. I wouldn't mind doing 17MM in Front but 2MM... Really ain't much. Thanks

 

I'm hoping we can all agree on 15mm or 17mm and don't lose anyone if we go one way or the other. I will do either but I dont think the group buy can have any variances.

 

Winger can make the definitive decision. There is only one way to go IMO.

I'd consider this if I was sure I wouldn't have to grind anything or have clearance problems with my 19" Centrifuge and stock sized tires (but no longer P-Zeros). I can't lower the car, so there's that.
