Coilovers — coil spring over damper units — are the most popular suspension modification for car enthusiasts wanting to lower their car, improve handling or prepare it for track use. In 2026, understanding how coilovers work, the difference between lowering springs and full coilovers, the legal requirements and what to expect from the installation helps you decide if coilovers are right for your car.
Lowering Springs vs Full Coilovers
Lowering Springs
Lowering springs replace the standard springs with shorter, stiffer units, reducing the car's ride height. They are fitted with the original dampers. Lowering springs are less expensive but combine the original dampers — designed for the original ride height — with stiffer springs, which can result in inadequate dampening and a harsh ride. Cost: GBP 100 to GBP 400 for a set.
Full Coilover Kits
Coilovers replace both the spring and damper as an integrated unit. They allow independent adjustment of ride height and dampening. Quality coilovers are designed specifically for the vehicle's weight and intended use, providing matched spring and dampening rates. Cost: GBP 400 to GBP 2,000+ depending on quality.
Adjustable vs Fixed Coilovers
- Fixed lowering: Pre-set height, no adjustment — less expensive
- Height-adjustable: Allows spring perch height adjustment to change ride height without changing spring rate
- Damper-adjustable: Multiple click adjustments to the dampening rate — from soft to firm
- Fully adjustable: Height, dampening and sometimes camber adjustment — premium coilovers

Coilovers and the MOT
Lowering springs and coilovers that do not significantly alter the vehicle's fundamental suspension geometry typically pass the MOT without issue. Requirements: Related: Big Car Tax Changes Coming to UK 2026 | Car Tax Changes UK 2026 | Tax My Car UK 2026 | Adaptive Cruise Control UK 2026.

Frequently Asked Questions
Q: How much is car tax (VED) in the UK 2026?
Car tax rates in the UK depend on your vehicle's CO2 emissions and list price. Standard rates start from £190 per year for petrol and diesel cars, with zero-rated VED for EVs. First-year rates vary from £0 to £2,605 depending on emissions. Additional premiums apply for vehicles over £40,000.
Q: How do I check if my car is taxed online?
You can check your vehicle's tax status for free on the Gov.uk website at gov.uk/check-vehicle-tax. You'll need your vehicle's registration number (number plate). You can also check via the Motor Insurance Database to verify road tax and insurance status simultaneously.
Q: Can I get a refund on car tax if I sell my vehicle?
Yes — if you sell or scrap your vehicle, you can claim a refund on any full months of remaining road tax. Contact DVLA with the V11 reminder letter or apply online at gov.uk. Refunds are usually processed within 4-6 weeks.
Q: Is road tax refund available when transferring ownership?
No — road tax does not transfer with the vehicle. When you sell your car, the tax is automatically cancelled and any remaining months are refunded to you by DVLA. The new owner must tax the vehicle immediately. As a buyer, always verify the vehicle's tax status before purchasing.
Q: What is the luxury car tax threshold in the UK 2026?
The additional rate for vehicles over £40,000 (list price) adds £410 per year to standard VED rates for years 2-6 of registration. This surcharge brings the annual cost for high-emission vehicles over £40,000 to around £600-690 per year. Pure EVs under £40,000 pay zero VED.
