Which 114.3mm hub interchanges with the front hub on the 2009 SS TC.

 

I am looking into this i dont think there are any we can bolt in but i do think we can maybe have aftermarket ones re drilled along with our rotors. if u had a sc/ss it would be easier because the abs is different and works with grand am hubs. I will let u know bc if we can do somthing i think evryone would agree to have more wheel options

 

The bore on the knuckle is the same as the SS/SC. ABS would be the only thing stopping you from using the Grand Am hubs, at least from knowledge of the subject.

 

I told you i was looking onto it. This kind of information is not easy to cross reference.

And to go along with what boostaddict said, 05/05 and early 07 are easy, they work with 03 Grand Am hubs, easy bolt in swap. The 09's use a very different ABS system, and currently i do not know of a compatible wheel bearing. I'm not sure it it doesn't exist, but from the people i've asked, i've been told that nothing readily available is compatible with the TC's brake system.

 

Have you looked in to any aftermarket hubs from like napa to machine new holes? i have been trying to see if any would work

 

There aren't any Napa's around me. I trusted in the experience of an incredibly talented shop, with a tremendously successful race team to do the work.

 

Idk just throwing ideas around
