Hi just wondering if anyone would know which of these would suit an a15 with h89 head best:

What RPM range will you be running? Higher RPM requires stiffer springs, but stiffer springs cost HP and increase wear. Will you be exceeding 6800 RPM?

haha prob not. I'm building up a mild daily driver

For a mild daily driver engine, I would use the stock A14/A15 springs. They are stiff enough to run to 6400 RPM, but light enough that they increase HP and fuel economy

All those springs listed are for extra-high RPM running, for example the lightest they have suitable for A-series is probably good for 10,000 RPM

Tom, I got a set of VW springs to suit the beetle engine from H&M Fermens on Boundary Rd at Mortdale for $20. I am using them in my daily driven A15 with stock cam. I had them installed by Graham Wilkins at Seven Hills when He serviced the head & his opinion of the springs were they were up to the job. I've even used the same springs with a mild cam with success. Crow cams Australia list a set of single springs for an A12 as well.
