Advice on windscreen for 944

[Mac944]

Hi,

I have a 944 S2 racing car (in fact it's a bit of a mix of 944 and 944 S2).

It currently has a very badly cracked S2 windscreen which I need to replace before my next outing this weekend.

Having received a few quotes it appears the S2 windscreen is about 3 times the price of the standard 944 windscreen. I understand the S2 is a more flush design and looks better but I was wondering weather there were any other differences?

Should I replace with another S2 or go for the cheaper screen? If I do go for the cheaper screen will I need anything else such as the seal or any additional mounts etc?

Thanks
