02 WRX front cailper guide pins
 

Where's the best place to acquire these? seen them ranging from £8 to £28 are they all equal?

Also the one of them is stuck fast in my cailper any tips on removing seized ones without heat or taking off the cailper?

Brake pad retaining pins?
I usually polish them up with some emery and the lathe, alternatively use a drill.
If you want to replace them but some stainless rod and drill the ends 👍, otherwise clean up your old ones and copper them up well.

if they are beyond saving then we stock new kits on the shelf...........

Thanks but to late, found a kit at Euro car parts.

From my experience 4points on the road is just fine. Saying you might as well kept the original belt is a debatable statement. The 4points held you in place way better than normal belts. Obviously I am not talking about track use. That's 6point all the way but fast road 4points do just fine. Just my 2cents.
And as a sidenote.. There are fancy 4points that can be easily upgraded to 6points. Sabelt for example.

Above????.

I bought my replacements as a kit from guys on ebay.
