idleboost spec TE37SL need a 5mm spacer for spoon calipers IF you're using stock rotors. It doesn't need any spacers if you are using the ballade 330mm rotors.

 

Thanks for the reply!

I was using the spoon caliper template a fellow s2ki member created and with a 5mm spacer added it was still not clearing. Maybe I was doing something wrong or didnt scale properly when printing but 5mm did not look like it would clear.

 

It definitely needs more than 5mm to clear spoons using stock rotors on idleboost te’s

 

100% just got around to fitting mine on the car and I needed a 12mm spacer to clear. I tried a 10mm and it was just too close.

 

I bet it was a little close too. I used a 15mm hub centric because they were easiest to source and I had a friend that told me his 10mm wouldn’t clear so i didn’t want to risk ordering a 12 and it not work but that’s good to know.
