so i'm in the market for calipers and settled on Spoon calipers. I test fitted my rim on a friends s2000 that has spoon calipers to check for clearance...

my front rim is a 17x7 +38 (5Zigen FN10-R) and the spokes clear the calipers with about 1 mm of clearance.

i wanna make sure that the calipers dont interfere with the rims; (ie heat expansion, hard cornering, etc.) this is my first time dabbling with calipers...will this be enough clearance? should i run a 2-3 mm spacer just in case?

i mm is not enough, caliper could flex under extreme conditiion, run a spacer to be safe

 

yes, running a spacer would be a much safer, 1 mm might be ok for clearance but its a chance i would not be willing to make

This is interesting. The rims should flex? The spoon calipers have 1mm or LESS clearance with the +35 SW388s. I couldn't even fit a credit card between the two. I never had any problems.

 

anything could flex if you put enought pressure to it.

Like i said, it's more likely to be the caliper itself that move out of line, knock back and flexing could happen if you track your car hard enough, i don't know how well is the construction of the spoon binder but i think the wilwood lite binder are known for flexing

 

I had about the same clearance with my endless BBK with fn01rc and my ccw and i never encountered any problems even when i tracked it.

for peace of mind i would run a 3mm spacer but i think that you dont need it...
