Pads for Hyundai Excel X3 front (vehicle shape).
Fits: Excel X3 front caliper.
What we’d fit.
Excel racing is short, hot and starts on cold pads. W5 is the standard circuit compound and handles a full sprint; W6.5 carries a higher ceiling and comes in from 50°C, which is the difference on lap one of a six-lap race.
WinmaX W5
WinmaX’s standard circuit model, and the default club racing and rally choice in the range.
View this padWinmaX W6.5
The standout for sprints and hillclimbs: close to 0.5 friction from a 50°C floor, so it bites on lap one. WinmaX call it their best rally pad.

This is TrackTheory’s recommendation for the Hyundai Excel X3 front (vehicle shape), not manufacturer advice — a starting point based on the published figures below and what we stock, not a survey of what other competitors run. Car weight, driving style and how long your sessions are all move the answer, so tell us yours and we’ll give you a straighter one.
Same shape. Very different pads.
Every compound below bolts into the same Hyundai Excel X3 front (vehicle shape) caliper. What separates them is operating temperature and friction — a sprint pad that needs heat in it will feel wooden on a cold first lap, and a road-biased pad will fade before the end of a long race. Figures are the manufacturers’ own published data.

Figures are the manufacturers’ own published data for each compound. Where a brand doesn’t publish a figure we say so rather than estimate it. From cold is our reading of each manufacturer’s published minimum operating temperature, not a separate rating they publish. Manufacturers test on their own equipment, so friction numbers are best compared within a brand rather than across brands. Not sure which suits your Hyundai Excel X3 front (vehicle shape) setup? Ask BuildBot or email us with your car, class and typical session length.
Where this caliper turns up.
Project Mu compounds (5).
WinmaX compounds (3).
One shape, every part number.
These part numbers all share the Hyundai Excel X3 front (vehicle shape) backing plate. The suffix is the compound (and plate thickness where the shape comes in more than one) — ask us or BuildBot which compound suits your discipline.
