Cost per Tenth
The mod-thread argument, settled with arithmetic: price any upgrade in euros per 0.1 s of 0–100 improvement. Power against weight, intake against tune — same ruler for everything.

Why price mods per tenth
Every upgrade claims to be "worth it". Price and gain live in different units, so the argument never ends. Divide the price by the tenths of a second it actually buys and every mod lands on one ruler. The results are uncomfortable in the best way: a €600 tune routinely beats €1,400 of lightweight wheels by a factor of twenty in straight-line value.
Use it as a budget sequencer, not a verdict on fun. Weight savings still transform braking and handling; the tool prices only the straight-line share, which is exactly the part people overpay for.
Reference run — 300 hp / 1,400 kg RWD
| Mod | Price | Tenths gained | € / tenth |
|---|---|---|---|
| Tune, +35 hp | € 600 | 5.1 | 117 |
| Intake, +8 hp | € 350 | 1.3 | 275 |
| Exhaust, +12 hp | € 900 | 1.9 | 477 |
| Bucket seat, −20 kg | € 800 | 0.7 | 1,143 |
| Forged wheels, −12 kg | € 1,400 | 0.4 | 3,333 |
FAQ
With the same power-to-weight model as our 0–100 estimator: time scales with kg per hp and a drivetrain launch factor. It is a comparison model, not a dyno — but because both scenarios use the same model, the difference between them is meaningful.
Percentages: removing 20 kg from 1,400 kg changes mass by 1.4%, while a tune can add 10% power for less money. Weight still pays off in braking, tires and handling — this tool prices only the straight-line share.
No — big power on street tires eventually hits traction limits the model cannot see, so treat extreme numbers as optimistic. For mild upgrades the comparison holds up well.
