Do most of the spacers come with extended studs or would you need to purchase those separately? sorry im new to all this thats why im asking. And what do you mean by swapping out the studs? Im going to definitely reference back to this post when I do this haha

 

Both are available. Either the one that comes with studs or the other type is where the extended studs need to be installed. My Eibachs have studs with them. In the link I put above, they have both types. Simply put them on OEM lugs and torque them down with the supplied bolts and then put the wheel on and then torque the OEM lug nuts. I do spirited driving a lot and mine have been flawless. Though, I never have taken it to the track so far. There is a new track opening up in my city later this summer so next year, I might be taking it there.

 

The type Rolla posted are referred to as bolt-on. They bolt on to the car and have new studs for the wheel.

The kind I mentioned are referred to as slip on. They are effectively sandwiched between the rotor and wheel, sharing the same lug. Typically need longer wheel lugs installed.

 

This is the picture I took over 2 years ago when I installed the spacers on stock height. It was with the OEM pilot super sport tires. Close shot of the gap with OEM suspension. Now, I have the Michelin Pilot Sport 4S tires with XL thicker sidewalls, which make the tires look more "meaty" especially on the sidewalls so there is a bit less gap now especially in the front.

 

I mentioned in my video, but bolt on slip on is a preference. It comes down to maintenance and proper installation.

If you can properly torque down a wheel lug, you can properly install bolt on spacers. People are put off by extra points of failure, but it really makes no difference IMO.

 

05RollaXRS,
Your great looks great man! I love the look that the spacers give. I also like how you put on beefier tires. Thank you for your help and knowledge on this topic I appreciate it!

 

LoSt180,
Okay thank you for comparing the both for me! It looks like I will try to pursue bolt on ones. They seem to be the smarter choice between the two.

 

Thanks man. Glad I could help.

 

Would you happen to have a photo of the current setup with spacers and new tires? Also what size spacers and tires?

I'm looking to do the same but with 305/30/19's in the rear and 275/35/19 up front.

 

Hey man, my tire setup is the same stock size. 275/35 rear and 255/35 front. My current setup is the following picture. The gap is a little less because the PS4S (XL) have more "beefy" sidewall at least when they are brand new. I will see how they wear-in as time goes by. I have 15 mm all around.

If you have wider tires then you would want 10 - 12 mm max so that the tires don't stick out past the fender.

 

Oh okay I wasn't sure if you went wider tires with the spacers. I may just have to do the tires first and see how it sits before looking into spacers. Thanks for the help!

 

You are welcome. Just a recommendation, I would say go with 295/30 in the rear on OEM wheels (assumption). It would also preserve the front/back width ratio. 305/30 might be a bit too wide for the stock 10.5 inch rear wheel and might make the tire bulge out a bit.I would recommend Pilot Sport 4S (XL). Great tires and so much better than the OEM PSS tires.

 

I'm glad you mentioned that......if a 295/30 will "fit" the stock rear (which is great), what size did you used for the "stock" front scenario, please?

 

Personally, I am OEM size front and back. If you want to go 295/30 rear, I would either go OEM size front or 265/35 at most on the fronts.

 

^^^^If I owned an RCF I would not go with 265/35/19 up front and 295/30/19 rear. It will throw off the stock stagger too much IMO. Stock wheel/tire OD is 26.0" in front and 26.6" rear. Upsizing the fronts to 265/35 would change that to 26.3" front and with the 295/30 it would be 26.0" out back. You don't want the front OD to be larger than the rear.
