When I purchased my car back in 2009 it already had an unknown cam and unknown valve springs installed. I have been putting this off WAY too long, but I am in the process of replacing them. I can't seem to find any type of identifying marking on the springs to aid in replacing with the proper type. I also don't know the specs of the cam to try to match a similar spring.

Any ideas what type of springs these are, or what a suitable replacement would be?

Thanks in advance.

They kind of look like BTR dual springs and titanium retainers. Hard to tell from just a pic. Pull one apart and see what the seats look like and weigh a retainer to see if steel or titanium. I stand corrected, they do not look like BTR titanium, slight curve to them. http://www.briantooleyracing.com/660...retainers.html , sorry about that good luck

I think I am going to replace them with these BTR springs

Anyone have any experience with them here? I have read lots from guys making bigger power and drag racing, but not much from the road course group.

Could be these PRC Springs?
