Suspension Accessories

Suspension Accessories

Suspension accessories are the small parts that decide whether a coilover or lowering spring set-up works properly or just rattles. This range covers helper springs, spring seats and perches, and the hardware that holds the assembly together. We choose to stock parts with consistent tolerances and finishes that survive Australian road salt, gravel and weekend track use, because a cheap seat or a mismatched helper spring will undo good dampers fast.

Shop by Vehicle

These accessories are sized to the suspension hardware rather than the car, so fitment follows your coilover or spring kit, not the badge. They suit common Japanese and European platforms running aftermarket coilovers or lowering springs. Check the individual product listing for confirmed compatibility, or contact us with your kit brand and spring dimensions and we'll point you to the right part.

Why these suspension accessories

Helper springs keep the main spring captive at full droop, which stops the clunk you get over driveways and big compressions on lowered cars. They also let you run a shorter or softer main spring without the spring going loose in the perch. Spring seats and perches matter for the same reason: a seat with sloppy tolerances lets the spring shift under load, which shows up as uneven wear and inconsistent ride height side to side.

The honest trade-off is that adding a helper eats a little stroke and adds a small amount of static height, so it's worth measuring before you order rather than after. We stock brands known for holding their dimensions and their coatings rather than the cheapest option available.

Fitment & Installation

Fitment depends on the kit you already have. Before ordering, check spring inner diameter (commonly 60mm or 65mm on aftermarket coilovers, but verify yours), free length, and the thread pitch of your damper body if you're replacing seats or lock rings. Note whether your fronts and rears use different diameters, which is common on strut-front platforms.

Most installers pull the strut out of the car, check preload and total available stroke with the accessory fitted, then set ride height and corner balance if the car sees track use. A spring compressor and basic hand tools cover most jobs. Budget for replacement hardware if existing lock rings or seats are seized, plus anti-seize on the threads. A wheel alignment after any suspension work is strongly recommended.

FAQ

Will these accessories fit my coilovers?
It comes down to spring inner diameter, free length and thread pitch rather than the car. Check the product listing for confirmed sizes, or send us your coilover brand and model and we'll help you match it.

Do I actually need a helper spring?
Only if the main spring goes loose in the perch at full droop, which is common on heavily lowered cars or short main springs. If your spring stays captive and there's no clunking, you don't need one.

Do I need an alignment after fitting these?
Yes. Any change to spring seats, preload or ride height shifts camber and toe, so book an alignment once the car is back on the ground and settled.

Do you ship suspension accessories Australia-wide?
Yes, we ship across Australia, metro and regional.

What's the warranty?
Warranty varies by brand and part. Check the individual product listing or contact us and we'll confirm before you buy.
