Custom Cages, BMW E46
Custom Cages build twelve kits for the BMW E46, spread evenly across the 2-door coupe, 4-door saloon and Compact. Cameron has worked through every listing on this page. The range starts at £954 for a 6-point National Spec CDS kit and reaches £2,463 for the UK full cage kits. T45 Multipoint and Step 2 International weld-in kits sit in the middle, and the Compact carries the most variety of the three bodies: four kits across three spec levels.
This guide covers the E46 only. The E30 and E36 guide is live already. The modern 1 and 3 Series and the classic 2002 and CSL will follow as the programme runs.

6-point National Spec CDS
The entry point at £954 across all three bodies. One kit per body style, CDS steel, 6-point spec. The first step into the E46 cage range without the price of a full Multipoint.
T45 Multipoint
Five kits across the 2-door, 4-door and Compact. International and Step 2 International spec levels, £1,674 to £1,854. Weld-in, needs a fabricator to fit properly.
UK spec
Full cages for the 2-door and 4-door at £2,463. No steel is stated in the listing title. Ring Cameron before ordering and he will confirm the spec.
The 2-door range
Four kits for the coupe and M3 bodyshell. National Spec CDS at £954, two T45 weld-in options at £1,674, and the UK full cage at £2,463. The two T45 kits carry the same price but different spec levels: International Multipoint and Step 2 International Multipoint. If you are building for a specific class and the regs draw a distinction between them, ring Cameron before ordering and he will check.
| Kit | Steel | Price (inc VAT) |
|---|---|---|
| 2 Door 6 Point National Spec | CDS | £954 |
| 2-Door International Multipoint | T45 | £1,674 |
| 2-Door Step 2 International Multipoint | T45 | £1,674 |
| UK 2 Door | Not stated in title | £2,463 |
Prices include VAT. The two T45 kits are at the same price; spec level differs. Ring 0115 9893488 if you need the detail confirmed for your championship before ordering.
The 4-door range
Four kits for the saloon. National Spec CDS at £954 and a UK cage at £2,463, plus two T45 Step 2 International Multipoint weld-in kits at different price points. The second T45 kit, at £1,854, is a more recent addition to the range and carries a higher build spec than the £1,674 version. Garreth’s advice is to ring and confirm which one suits the championship before ordering if you are building for national-level competition.
| Kit | Steel | Price (inc VAT) |
|---|---|---|
| 4 Door 6 Point National Spec | CDS | £954 |
| 4-Door Step 2 International Multipoint | T45 | £1,674 |
| 4dr Step 2 International Multipoint | T45 | £1,854 |
| UK 4 Door | Not stated in title | £2,463 |
Prices include VAT. Both T45 kits are Step 2 International spec, at different price points. If your class specifies the exact bracing level, confirm with Cameron before ordering.
The Compact range
The Compact has four kits and more spread than the other two bodies. National Spec CDS at £954, a CDS weld-in at £1,735, a CDS bolt-in at £2,154 and T45 Multipoint at £1,854. The bolt-in at £2,154 is the only kit in the E46 range that fits without a welder. Note that it costs more than the T45 Multipoint at £1,854: the bolt-in premium is real on this chassis.
| Kit | Steel | Type | Price (inc VAT) |
|---|---|---|---|
| Compact 6 Point National Spec | CDS | 6-point | £954 |
| Compact CDS | CDS | Weld-in | £1,735 |
| Compact International Multipoint | T45 | Weld-in | £1,854 |
| Compact Bolt-In | CDS | Bolt-in | £2,154 |
Prices include VAT. The CDS bolt-in costs more than the T45 Multipoint on this chassis. If you need a fabricator-free install, the bolt-in is the route. For maximum cage spec, the T45 Multipoint is the one to go for.
The fitted photos here show the Compact International Multipoint T45 installed in a Compact bodyshell. The build fills the rear of the car properly and the main hoop bracing is visible through the rear side windows when fitted. Real install photos like these are more useful than a render when you are trying to judge how a cage sits in the car before committing to an order. Ring 0115 9893488 if you want to talk through the Compact fit.
The E46 range covers sprint and track day use through to national circuit racing, and the right kit depends on the bodyshell and the championship as much as the steel choice. Ring 0115 9893488 or use the contact page and Cameron will confirm the exact kit before you order.
Common questions about the E46 range
What is the 6-point National Spec kit?
Custom Cages’ naming for their entry-level E46 cage, available for the 2-door, 4-door and Compact at £954 each. Six mounting points, CDS steel. If you are building for a specific class, tell Cameron the championship name and he will confirm whether the National Spec kit meets the requirement or whether you need to step up to a Multipoint or International.
Why do two of the T45 kits for the 4-door have different prices?
Both are Step 2 International Multipoint T45 kits for the 4-door, at £1,674 and £1,854. The price difference reflects a higher build specification on the more recent addition to the range. Ring 0115 9893488 and Cameron can go through which suits your class before you order.
What steel is the UK cage built in?
No steel specification is stated in the UK 2-door or UK 4-door listing titles. Ring 0115 9893488 before ordering and Cameron will confirm the spec for you.
Does the Compact bolt-in really cost more than the T45 Multipoint?
Yes. The Compact Bolt-In CDS is £2,154 and the Compact International Multipoint T45 is £1,854. The bolt-in costs more because it fits without a welder, which saves the fabricator fee. If you are not concerned about fitting it yourself, the T45 Multipoint delivers more cage for less money on this chassis.
Does this page cover the E46 M3?
The 2-door kits listed here fit the E46 coupe and M3 bodyshell. If you are building an M3 and want to confirm fitment before ordering, ring 0115 9893488 and Garreth will check the exact spec against the car.
Are there kits for other BMW models?
Yes. The E30 and E36 have their own guide already live at SportSeats4u, and the modern 1 and 3 Series plus the classic 2002 and CSL range will follow. Ring 0115 9893488 if you need a kit for a BMW that is not covered yet and Cameron will tell you what is available.
Where to go next
For the steel decision on its own, our T45 vs CDS roll cage steel guide covers what the Motorsport UK specification actually requires and where T45 earns its place over CDS. If you have an E30 or E36 alongside the E46, the E30 and E36 guide is live too. The full Custom Cages range covers every other make we hold.
