Default A-Arm spacer question

I've noticed that when I install the spacers outboard of the a-arms "by the book" with a 1mm to the rear and a 3mm to the front, that the a-arms are bound up and do not swing free. This prevents the sway bars from working optimally as well.

The binding is definitely from the pinching and not from the pins themselves as I've reamed the holes and the arms swing free when I'm just holding the ends of the pins.

Anyone else experience this? What did you do?

You can see below that the arms will stay in the 45 degree angle position and not drop down like they should.

Sand down the spacers a bit. I had to do it myself. 5 minute fix!

im curious to why your worried about it, the cars suspension will never reach those angles... seems like a outta sight outta mind issue and not a actual functional problem. Just my .02

Can anyone tell me the screw hole spacing on the rear suspension mount. I am looking for a mount w/30mm spacing for a project. Thanks.

I had the same on mine. Didn't worry about sanding it as I know it will wear down by itself. I didn't want to remove too much from the spacers and induce any undue slop into the A-Arms

I replaced the plastic spacers with aluminum spacers. I always run .5mm less than what the manual states and have no slop.
FrontF 3.5mm, FrontR 1mm; RearF 2mm, RearR 2.5mm

I just picked up the 3racing DJC's are they as good as spec-r brand? They were the only ones I saw in stock.

FWIW, I rebuilt both of my S1s over the weekend. Lots of things needed fixing.

Probably the most odd was the binding/wobble in the left rear wheel. Traced it back to the "Sport" drive shaft on that corner. The shaft was not able to rotate straight as the shaft would never actually straighten out. I found that it had a set screw backing out of the center pin in the connection.

Here's the thing, I checked my other drive shafts and they didn't have this set screw. I checked the manual (it shows you have to build them, which we don't) and it doesn't show any set screw. For some reason, someone in China decided to put a screw in this one and it was backing out.
