Mugen Carbon Fibre Rear Spats Honda Prelude BF1 26+

Mugen Carbon Fibre Rear Spats Honda Prelude BF1 26+

Mugen’s carbon rear spats (rear diffuser) fit beneath the rear bumper corners of the BF1 Prelude and flare outwards, widening the rear and giving the car a planted, purposeful stance.

They are made from dry carbon with a gloss clear coat to match the rest of Mugen’s Prelude aero. They are designed as part of Mugen’s full rear package, so they can only be fitted together with the Mugen sports exhaust and its matching carbon rear diffuser.

Installation

Mugen quotes approx. 1.0 hour to fit, working to its installation instructions. Important: Mugen states the rear spats cannot be fitted on their own or with the standard silencer. The Mugen sports exhaust and the matching carbon rear diffuser (84120-XPD-K0S0) must be fitted at the same time or already be on the car. Professional fitting is recommended.

Can I fit the rear spats on their own?

No. Mugen designed them to work with the Mugen sports exhaust and the carbon rear diffuser 84120-XPD-K0S0, and they cannot be fitted with the standard silencer.

Which rear diffuser do I need?

You need the diffuser for the Mugen sports exhaust, part number 84120-XPD-K0S0. The standard-exhaust diffuser (84120-XPD-K1S0) cannot be used with the rear spats.

Is this part of the Mugen Prelude Spec III kit?

Yes, it is one of the carbon parts used in Mugen’s limited Body Kit Spec III. The Spec III kit itself was a 16-set lottery release and has sold out, but the individual carbon parts can still be ordered separately.

Do they need painting?

No. They are supplied in exposed dry carbon with a gloss clear coat.
