FAQs
Will the ride be harsh?
Unloaded ride firms up, but tuned correctly it stays safe and comfortable when loaded.
Pre-reg vs post-reg?
Pre-reg = federal compliance before rego. Post-reg = state engineering with rego update.
Need tyres or brake changes?
Tyres must meet new load index. Brakes must be in excellent condition; we’ll advise if upgrades are required.
Does it affect insurance/warranty?
We supply documentation for insurers. Warranty remains subject to manufacturer terms.
How long does it take?
Workshop fitment + alignment, plus time for engineering paperwork and rego processing.
