as above

which would be better suited for a fast road car running around 450bhp?

4032 is a high silicone material (low expansion) that can run tighter bore clearances.
2618 is a high(er) expansion material typically used in higher output engines.
4032 will be quieter than 2618
You would probably be ok with the 4032 if you don't plan to go mad in the future.

generally speaking then 4032 is better suited to road use cars and below 500-550ish

JE's have often been described 'like a skeleton *****ng in a biscuit barrel'
Mahle produce very good pistons for the money.

To be honest Mahle pistons is where you want to be at,there are a lot of company's that make pistons but I definitely think that the Mahle brand is a very good compromise between quality and reliability.its the go to piston for a lot of top engine builders.SJ.
