Anyone use this? Is it as good as Castrol?

Well, PJ has spoken. No further comments required.

I bought some jackstands from these guys and they are obviously big proponents

I know that several race teams are using it

Imgt3 could probably chime in or provide more info

I use it. Converted from Blue last year and was hesitating between this and the SRF. Decided on the Prospeed because of the 500ml bottle v. the 1 litre for the Castrol. They are both priced the same.

Saw a tweet from Pacific Western Performance recently that said that they carried it (in Canada), but I could not find it on their web site

Got mine for IMGT3, and the service from Chuck May was excellent.

Jeff is a great guy, I will talk to him about it as well.

Prospeed is excellent brake fluid.

Got some from Jeff too. Will compare with Castrol srf in near future, esp in the heat here...

BBMGT3

I got it, loved it, fantastic fluid. Have to switch out because I can't find any where I am and can't contact IMGT3

Got it and use it in all my cars. Will be switching the 4.0 over to it in the coming up weeks. We also have been using Prospeed in BimmerWorld's racecars since 2009. Never had an issue with it and it always has performed as advertised.

Seth, how does it compare to Castrol?

We have the ProSpeed 683 in stock.

I use Prospeed 683 for the last year. Zero issues. It is better on brake part seals than SRF but it is less compressable and less oxygen content.

thanks Mike.

Just ordered some from Apex! It wouldn't give me the Rennlist 10% off though . . .
