I've put these spacers on my Audi Quattro's in the past and I found that hub-centric spacers are needed to avoid any wobble or vibration. I would assume that Suncoast only sells these types of spacers? You're not the first to feel a vibration at speed and hopefully this will be easily resolved. Of course you can easily check by simply removing them to see if the vibration disappears. My after market wheels seem to fill the space by having a different offset, but I've not measured them.

 

Thats the thing - these spacers are also hub centric so the weight should be resting on the lip and not so much on the lug nuts. I may try and take them off tonight to see what the difference is 😊

 

 

Thankfully, it was just balancing! Drives at speed perfectly now 😁😁 So good. I would suggest that when you put them on, ensure you get all four wheels balanced and ask them to be super meticulous. Turns out 2 wheels were 0.25oz out (very little) and that is what caused it to judder.

Will take those pictures and upload them in a couple hours so you can see how it sits.

 

Here you go!

 

Glad to hear that it was something simple and got worked out, the wheels fill in the space much better now!!

 

Thanks buddy! Yep makes all the difference. Now I need to ensure the aftermarket summer wheels I get will be the right offset to match 😊

 

Anyone used spacers on a stock 997.1 RS? What sizes will fit without rubbing with the standard sized MPSS tires (I realize they come equipped with Michelin Sport Cup tires, but no one seems to use these on the street due to the accelerated wear rate)?

 

I am certain this has been done - have you checked the 997 forum?

 

 

They look pretty good, hubcentric too - don't see that there would be a huge amount of difference between brands though.

What do you mean by install - you talking about the tire balancing and putting the spacers on? If so, putting the spacers on is a couple mins per corner ensuring all is lined up, clean and attached. Balancing the tires is about 25 mins at a tire shop.
