You mean County. Yes, my 1293 has them which I bought from Bullmotifminispares. about 3 years ago. Not had any problems with them.

For general rebuilds and moderate street performance builds they are OK but they are not a performance piston.

What would you recommend?
I'm. Upgrading the cam
Kent 266 and reboring to 020
I've seen omega pistons but Really expensive

P21253 is fine for up to c.6500 rpm and is listed as the correct replacement for the original Cooper S pistons.

As Moke Spider says, 998 County pistons are ok in mild tune.
I use circlip type ones in up to 70/75hp engines. I have had problems with the interference fit pin types and wouldn't use them in anything.

You've a few good sensible choices here I feel.

 

The County ones, which are OK.

 

There's also the Hypertec ones, which again are not a performance piston (in the std range) but will take quite a beating. They also have a flat top version which is a performance piston.

 

AE ones are ~OK~ I guess, but wouldn't be my choice.

These were bought out by AE.

From my own experience, they were once a great piston and for many engine builds, the go to piston, but I've been bitterly disappointed with them in about the last 10 years.

The Calver ST pistons are good.

 

Hypertecs are the same piston, only 1/4 of the price.

These guys are the distributors for them;-

 

https://www.precisionintl.com/

however, from what I've heard, you may find dealing direct by email, hit and miss. Pick your time of day and ring them.

 

These also use the original sized imperial rings, so there's a very wide range available for them, though the Hastings they can supply are OK.
