What it does
25 chassis, 36 build slots, 63 priced parts, 21 compatibility rules and 7 running costs. All of it free.
The phased plan
Five phases in the order you should buy them, with the reasoning attached to every step. Each slot shows a recommended pick for your goal level and the alternatives in that slot, each with honest pros and cons rather than marketing copy. Running totals per phase and overall.
Compatibility that knows what is in your build
21 rules, evaluated against the contents of your plan rather than against your chassis. That distinction is the whole feature: the most-reported reason performance parts get returned is that they fit a standard car and not a modified one. Fit an angle kit and your usable wheel offset window moves. Add a power adder and the clutch, axle, fuel, tune and cooling rules all fire. Each warning says what will happen, what to do about it, and how confident we are.
Confidence levels instead of promises
Every rule and every part is tagged verified (we or a cited source confirmed it on this chassis), community-reported (owners-group or forum consensus, linked), or general principle (true in general, measure your own car). We never claim a fitment guarantee.
The consumables and running-cost budget
Tires, fluids, pads, fuel, entry fees and a breakage allowance, shown per event and per season next to the parts total. In a documented year-one drift budget this was about a fifth of total spend, and it is a blank column across every competitor we looked at.
Chassis-specific everything
Weak points with the phase they belong in, a buying checklist with what each problem costs to put right, the wheel offset window and how an angle kit moves it, engine and swap options with rough costs, import and steering-side notes, and per-slot notes where your chassis needs something unusual.
Pre-event checklist, generated from your build
Not a generic list. If you have an angle kit it tells you to cycle the steering to full lock and look for witness marks. If you have a hydraulic handbrake it tells you to bleed that circuit. If your power target is high it tells you to carry a spare axle, and it names your chassis' own weak points.
Plan becomes log
Mark a part installed with what you actually paid. The plan becomes the build history and planned-versus- actual appears per phase.
Share and fork
Every build gets a public page you can share, and anyone can fork it and change it. No competitor we found lets you fork a build.
Free tools
An angle kit offset checker, a drift budget calculator, a tire cost per event calculator, a welded-versus-LSD decision tool, and a what-breaks-first lookup by chassis and power level. No account for any of them.
Where the data comes from
63 parts across 19 retailers, every price a market range with the date it was checked. 21 rules, each with its sources listed on the page where it fires. 25 chassis, 15 of them with full sourced depth. Nothing in the catalogue is generated - it is written, cited and dated, which is why we can show you the sources instead of asking you to trust the output.
Prices are market ranges with the date they were checked, not live quotes. We do not have a live price feed, so we show you a range and send you to the retailer for the real number rather than pretending to know it.
