Used brake calipers vary between vehicles - and whether you call it used, second hand or a replacement, matching the right one matters. These are the details breakers need to match the right part to your car - our request form asks them so you only hear from suppliers with the correct part:
Yes, the RX-8 has brake calipers on all four corners — disc brakes were fitted all round on every variant sold in the UK. The RX-8 used a rotary (Wankel) engine rather than a conventional piston engine, but its braking system is entirely conventional, so used calipers are readily available from breakers.
The RX-8 ran from 2003 to 2012, with a facelift arriving for the 2008 model year, and the brake setup can differ across that boundary. Whether a pre-facelift caliper crosses over to a facelift car is not guaranteed — confirm against your exact registration with the breaker before buying. Engine output (192 bhp vs 231 bhp versions) also influenced brake specification, so make sure the breaker matches both the year and the engine variant of your car.
Yes, engine power is relevant here — the higher-output 231 bhp RX-8 was generally fitted with larger brakes to match its performance, so the calipers are not necessarily the same as those on the 192 bhp car. Always tell the breaker which engine variant you have, not just the year, to make sure you get the correct caliper. Mixing calipers between power variants risks mismatched braking performance and potential safety issues.
Trim level on the RX-8 — whether that is a standard, PZ, Kuro, or other UK specification — does not change the brake caliper fitment in the way that engine output does. The key variables are the model year (pre- or post-2008 facelift) and the engine variant (192 bhp or 231 bhp), not the trim name. Bear in mind that a caliper from a different trim might look slightly different cosmetically, but confirm the mechanical specification matches your car with the breaker.
Yes, always specify nearside (NS, left-hand side) or offside (OS, right-hand side) when requesting a caliper, as front and rear calipers on the same axle are handed — a nearside will not fit the offside. Also state whether you need a front or rear caliper, as these are different parts entirely on the RX-8. Getting this wrong means the part will not fit, so be precise when contacting the breaker.
Visual similarity is not a reliable guide to fitment — internal bore size, mounting points, and hydraulic connections can differ between years and engine variants even when the caliper looks alike. The safest approach is to give the breaker your full registration number so they can verify the exact specification of your car. Never assume a caliper fits based on appearance alone; always have fitment confirmed against your registration before purchase.
