the rotary aviation 2 piece 2mm seals are good i think. i used them in my s4 t2 engine and i have no complaints. it makes awesome compression and it was broke it in about 500-600 miles, although i used fairly low mile housings. but for the price you can't beat them. i've noticed they're in stock now and i think shipped they're $182, but that's if you live in the USA. shipping is a little higher for international orders. check em out at www.rotaryaviation.com.

"Best" is relative. What do you want? Strength? Easy break in? Soft seals that don't damage the engine if they let go?

For most people, stock is "best".

But there's nothing wrong with the Atkins or RA seals.

OEM seals have been known to handle high amounts of boost. Its all about tuning.

The seals from RX7 specialties are Racing beat, I have some 3mm RB seals in my car and I didn't really let them break in, but their still hauling ***.

Titanium? As far as I know they are very abrasive and will shred the aluminum in no time.

I would like to think that Rotary Aviation makes the best seals, because those are the ones I bought. Suppose to be way more durable, RA claims 30psi can be obtained on their 2mm seals.
