BuildSideways

Every chassis we plan for

25 rear-wheel-drive platforms, each with its own weak points, buying checklist, wheel offset window and per-slot notes. Sorted so the ones that make the best first build come first, not the ones that look best on Instagram.

Used prices are market ranges with the date they were checked. "First build" is 1 for an easy first car and 5 for one you should own after you have built something else.

If you have not bought a car yet

The three things that actually matter for a first build, in order: how cheap the car is to replace when you damage it, whether the parts are on a shelf near you or on a boat from Japan, and whether it has enough torque to hold an angle without being worked. On those three, the honest answers are the E36, the S13 or S14, and the 350Z - not the cars with the best reputations.

A car you can buy locally with no import process is worth a lot more than it looks on paper. So is a chassis where somebody has already published a setup sheet. S13, S14, E36, E46, MX-5 NA, GT86 all score 5 out of 5 on parts availability, which in practice means you will not lose a weekend waiting on a part.

In the planner, still being researched

These work in the planner and have real weak points and checklists, but they do not yet carry the depth of sourced content the pages above do, so we keep them out of search rather than publish something thin.
