Just to elaborate why I think they warrant $160 for a 2 wheel kit.

A Branded 2 wheel pair of spacers of various sizes can run $60-$120.

But for $160 you get the parts to make 14 different offset sizes for those 2 wheels. So this helps you get a more precise fitment, and if you don't need the full 30mm then your left over with some slipons that you can use for fine tuning the other 2 wheels.

If you bought 20mm and then wanted to change wheels, camber, tires, or right height and need to re-buy spacers you then you've spent on just as much by the time you buy more sets to replace them.

So at $320 for 4 wheels yeah it sounds high, but you'll never need to buy different set for the progression of your cars wheels sizes over the time you have the car.

As well as with 2 full sets (4ea) you will gain even more sizes than just 14, because you'll have now have duplicates of each slip on when used together will make more combinations.

They are also machined with the GS stock size 60.1mm hub-centric centerbore.

 

i was under the assumption and i could be wrong that you get 2 bases (with studs) and then the "plates" to slip the extra spacers on therefore you wouldnt have 2 bases to mount the fronts on.... i could be wrong but thats what the pics look like

 

You are correct. The 15mm spacers have the studs on them, the other 3mm, 5mm, 7mm included are slip-ons with no studs.

So if using on the other 3 sizes without the 15mm base spacers they will slip-on not bolt-on. Which 3/5/7mm is small enough to get away with on stock length studs individually, but I would never stack all three for 15mm.. Anything over 10mm needs to be bolt-on or extended studs.

The slip-on's don't bolt-on to the base 15mm studded spacer either, you bolt the 15's on first, then add the slip-ons as needed up to 30mm, but the 15mm studs are sized long enough to account for the additional 15mm of slip-ons. So no worries there.

Not for everybody's setup, but I feel having 14 offset choices vs 1 offset choice is where the extra money sees some value. Regardless if the unused spacers are used on the other 2 wheels.

I my situation 1 set (2 wheel) is perfect, as I'm using 25mm on the front and only needed 5mm on the rear. Although I now have Aimgain front fenders that are wider that stock, so once they come back from paint I am going to re-lip/barrel my front wheels and also need less spacer down to a 15mm.. So again one pair purchase worked initially and can also redo my cars setup without buying any more spacers.

Again not for everyone, but as an option for some it is a high quality spacer kit that has 14 offset options is all I'm saying.

 

Anyone else have recommendations on where to go for extended studs?

Might go with these:

Is 50mm too much? And do |I need open ended lug nuts?

 

For individual studs not associated with a branded spacer kit, I would not buy anything but ARP.

 

I went ahead and bought 45mm Ichiba studs. I should be fine right?

 

Ichiba is quality. You'll be good.

 

Do I need open ended lug nuts if I got the 12mm spacers and 45mm extended studs?

 

Maybe.

Depends on your wheels and your lug nuts.

 

This is my current set up, 245/35/19 all around.

I'm thinking that these spacers will help me quite a bit! I definitely need hubcentrics because the spacers that I'm currently using cause a lot of vibration over 55 mph. $160 is on par with some others that I've considered, I suppose I would just need another set of ARP extended studs for my rear wheels so that everything looks square.

 

Good investment. Looking good

 

To much poke up front and sunken in the rear.... what size spacers are you running? on my G35 rims 19x8 with 235/35/19 i ran 12mm up front and 22mm in the rear and they fit almost perfectly
