I have a 2012 (yes they came out that year in Australi!) rwd gs350 f sport with 19" rims

Am looking to get 20mm H&R spacers for the rear wheels. Doing some searching, there only appears to be the 'bolt on' type and not the version which comes with extended studs for you to replace. Is this correct? If i search for 15mm spacers then i can easily find the version with the extended studs...

If someone could also confirm the model number i need is 'h&r 4065600' ?

When i search the following model number also comes up 'h&r 4065601' but im not sure what the difference is between the two...

Thanks!

 

4065600 is the right part number for the 20mm with its own studs (adapter style that bolts to your existing studs, then bolt wheels to the spacer studs). From H&R these are known as DRM style.

The one where you have to replace the studs is known as the DRS style spacer form H&R https://propartsusa.com/products/h-r...-40656014-4438 (note: I am not certain this part fits, though the descriptions indicates it would).

 

Great, thanks for that. I guess the million dollar question is whether to go bolt on or extended studs.

Has anyone actually experienced failure with H&R spacers?

 

I used the bolt on ones mentioned above (part # ending 600) for over 30k miles. I used anti seize on the hub and the back of the spacer when I mounted them and they were easy enough to remove when I swapped wheels (I live in a year round warm climate so can't speak to how it is in rust/snow climates).

They never failed and the bolts on the spacer were still properly torqued when I went to remove the spacer.

 

You’re not looking hard enough. I had H&R in their DRS series in a 20MM.

DRS series is where you replace your stud with their longer stud.

 

Im in Australia, so my choices are limited, a majority of google search results are for overseas sites.

To figure out if it will suit my car, would i just need to confirm the measurements? So i would look for H&R DRS 20mm 5x114.3, 60.1CB, for studs 12x1.5mm ?
