Yes, I agree. The laws dictate that wherever the engine is placed, negative acceleration will place more weight on the front axles, hence needing more brake force up front.
And I'm extending this further to say that in rear-engined cars, the weight transfer is not so extreme such that the weight distribution is more like 70/30 vs 85/15, hence the need for stronger brakes in the rears to effectively take advantage of this property.
What brakes are you using now? Same as my 944 setup? How does it feel to you? Overall is good to me, but I find the fronts a bit too strong, or should I say the rears a bit weak? Hence the question of proportionating valves.
Sprint.
