They are 60mm each per side ,no make on them but appear to be well machined ,I bought them in error a while back on ebay ,I wanted smaller as i had a set of alloys I wanted to use as they had decent tyres on that wouldn't fit my modulars but after a couple of weeks I noticed the sidewalls were all cracking up at which point my brother donated the modulars and tyres from his disco to me so I removed them as the protrusion outside the arches would have been quite large with 265's on.
