Build
Forums argue; arithmetic decides. The build journey runs from scoring the whole plan to engineering individual corners — every step free, every method shown.
In this order
Score the plan first
carbuildcheck grades the whole build — order, risks, budget sanity — before parts get ordered.
Sequence mods by value
Price every candidate in euros per tenth of 0–100. The cheap tenths go first.
Engineer the suspension
Spring rates from ride frequency and motion ratio — the method, not folklore.
Check the gearing math
What a final drive or tire change does to cruise rpm and per-gear speeds.
Make it stop properly
brakepadfinder matches a pad compound to how the finished car will actually be driven.
The full kit
Cost per Tenth
Every mod on one ruler: euros per 0.1 s of 0–100.
Spring Rate Calculator
Ride-frequency method with motion ratio, metric first.
Gear Speed Calculator
Speed per gear, cruise rpm, top speed from exact gearing.
Power-to-Weight Calculator
kg per hp — the number that predicts pace.
Tire Size Comparator
Diameter, speedo error and true speed for any two fitments.
0–100 Time Estimator
What the finished build should run, before it exists.
