I am doing some lapping once a while, (about 10 times in a summer, 10 full days). Wich brake fluid would you recommend ?

Car is a 2003 996TT

Thanks

 

Castrol SRF

 

No Castrol SRF available where i am at now...

 

ebay- search " Castrol SRF" and there are 3 liter multipacks for 189$ available. Kevin

 

Castrol SRF is in a class by itself-the best racing brake fluid you can buy. Second place would go to the Motul Racing, at about half the cost. Third would go to ATE Blue, at half the cost of Motul. The Motul 5.1 would be my fourth choice (lower wet and dry boiling temperatures than the ATE). Given that you want to at least bleed the calipers after every lapping day and you can't (or shouldn't) re-use leftover fluid from an open container, the Castol gets even more expensive, but nobody ever said this was a cheap hobby.

 

But I know a place that ships pretty quick... cheapoilstore.com .. try this link

Motul RBF600 brake fluid

 

AP Racing 600 is also an excellent choice.

i don't think porsche recommends DOT5 brake fluid. It'd probably do harm to the ABS and brake hoses.

so, between the two, i would say RBF600.
