Motorsport Harness Fitting

Fitting a harness to your roll cage

While searching our suppliers website (TRS Harnesses) I came across this great guide to correctly wrapping harnesses around your roll cage rather than using eyebolts and buckles. Aside from the obvious weight saving there are other advantages such as a better harness angle for safer installations…

Weight Saving:

By wrapping the shoulder straps around the roll cage the driver can quickly reduce the weight of the car by two snap hooks, two eyebolts and two backing plates. This combined weight saving is 0.568 Kg per harness, or 1.136Kg if you are in a rally car and have two harnesses.

The weight saving can be further increased if you can also wrap around the roll cage on the crutch strap anchorages too. Potentially on a 6pt harness by wrapping around the roll cage on the shoulder straps and on the crutch straps you could save 1.136Kg per harness or 2.272Kg for a driver and a co-driver.

Lets add all these weight savings up for a typical 6pt saloon / rally car harness. 1.136Kg saving on the hardware and 0.17Kg on webbing. That is 1.3Kg per harness, or 2.6Kg in rally cars who have a driver and co driver.


When wrapping harnesses around the roll cage there are several safety considerations to be aware of.

Always make sure that the webbing passes smoothly through the seat opening and is not chaffing on any seat mounts or sharp edges. Sharp edges can cause the webbing to abrade or cut. Always make sure that the 3 bar slide is as close to the harness bar as possible. This is important because a loose 3 bar slide can cause slippage. When wrapping around the roll cage always make sure that you remember the final locking loop. For a pictorial explanation of how to correctly thread up, please click this link. Once you have done the final locking loop make sure that you have at least 10-15cm of web as a tail. Excess webbing can either be neatly rolled up and cable tied out of the way or cut short at the TRS factory at point of order.

Ferodo DS Series Bedding in Procedure


Below is the procedure taken from Ferodo direct with regards to their DS series pads.

The aim is to bring the pads to full race temperatures, but slowly (too quick bedding results in glazing). This is done by a series of laps where full speeds may be attained but lighter braking pressures are used (i.e. the driver applies the brakes earlier). It is important that the pads are allowed to cool after the bedding process before racing. Ideally the pads will arrive at temperatures in excess of 500°C during the bedding. Pads smoking during the cool-down is not a cause for concern. Specifically for DS1.11 and DSUNO temperatures should arrive at between 500°C and 700°C (as an indication: green and orange thermal paints applied to discs to turn white completely).

Perform at least 15 trial brake applications, initially with reduced pressures (50% of the normal that might be used for that same brake application were it to occur under race conditions) building up to full decelerations after the 15 applications. To shorten the procedure applications can be made along the straights as well as at corners.

On completion of the trial applications, return to the pit lane. Inspect the surface of the brake pads from the two wheels that have been working the hardest. There should be evidence of contact over the full pad area, but without glazing. The pads are now ready to race. Whilst it is recommended that pads are inspected after bedding, if time does not allow this and paragraph 1 has been carried out appropriately, so long as a short period of time has elapsed to allow the brake system to cool (ideally to below 100°C – this might take in excess of five minutes), the pads will be ready to race.


Mintex M Series bedding in procedure


Please follow this official guide.

Ensure all braking components are clean and free of grease by applying solvent such as Brake Cleaner prior to bedding in.

Step 1.

3 to 4 light brake applications from 30-0mph.

Step 2.

M1144  6 to 7 steady applications from 70-30mph.

M11558 to 9 steady applications down from 90-30mph

M11669 to 10 steady applications down from 90-30mph

Step 3.

Leave to cool for as long as possible. The brake pads are now ready to use from cold.

Fiesta R1 Build – MP Motorsport

Fiesta R1 Build

So the Fiesta R1 build is coming to an end. This is the vehicle we travelled almost 1000miles to build back in May. The Mintex F4R brake pads have arrived after a 5 week wait (and then sent straight onto Denmark!) and the Bilstein suspension has been fitted. Next up was the glass and engine kit – which as you can see are now in. We have included a mock up of the sticker set at the bottom of this post, however we will provide photographs once the car has been to the sign-writers and is complete.

The first event for the car will be on the 15th of August at the Gjønge Minirally in Denmark where it will compete over 60km of stage distance, however there will be a shakedown prior to this to do a systems check. Jon from ShawSpeed will be over there to keep a watch and ensure everything goes as smooth as possible.

You can keep a check on the results of the rally here. We will of course update you after the event with some photographs and videos of the Fiesta R1 in action.

Enjoy the photographs and if there are any questions about the Fiesta R1 Build please don’t hesitate to contact us. MP-Motorsport – Good luck, and here’s to a good successful first outing!

Powder Coated Goodness…

Just received a batch of suspension parts for Joe’s Focus RS. They were powder coated by Fastline Coatings in Preston. They’re looking rather good now!

DM PREP / SHAWSPEED – Fiesta R1 Build

Hello all.

Just this week got back from 5 days in Denmark where we were building a Fiesta R1 for a rally team called MP Motorsport – Prior to this they have a Puma running around 200bhp using a ShawSpeed 1.6 Sigma. Unfortunately they crashed the car into a tree.. and then were hit from behind pretty much making the car and cage scrap.

So we were called in to build their new car – It’s not hugely quick but it is built to FIA regulations for the R1 class. If you ever have any work done by me (DM Prep) you’ll find I’m a little bit OCD and never really satisfied – so it was a bit tricky to build this car to my standard within the timescale we had – but luckily we managed it.

Taken from the M-Sport site “the R1 is set to become the first step of the ladder for competitors looking to start out in the Fiesta rally family. The base kit is designed to provide all the safety features required and when combined with the various option kits gives competitors with a 3 or 5 door car the chance to add items piece by piece until they have an R2” ”

Put simply it is 130PS, 152NM torque – Bilstein Suspension, Eibach Springs, 4.6 CWP, T45 Cage and all the safety gear required.

By the time we had arrived the team hadn’t taken delivery of their dampers, so we’ve left it with them to fit.

Anyway – Here’s a few photos, and a few photos of the brewery tour we managed to squeeze in! as well as a walk around a car collection in Denmark.

It was a mammoth road trip – took around 18hrs in total with about 3 stops for the toilet!

Bare in mind this was a Focus ST Estate – It was pretty full!




Anyway  – we arrived and we were greeted by this – Freshly painted caged shell. It’s a bit of a serious cage – and should be due to the fact it’s being used in competition. It also makes it a pain in the bottom to fit the dash and heater box back in – with an R2 fiesta you don’t use the original heater box – much easier.




On with it and fitting the interior and auxiliary looms – I’ve jumped a few steps such as silver circling it etc but didn’t really have time to take photos! My bald swede getting stuck in the cage no doubt..


Extinguisher and piping in – starting to lay the aux loom.


Brake pipes going in 



Control Panel, Handbrake back in



Tank guard on, prepped and taped up to stop any stones getting in and rubbing through..

MP Motorsport Fiesta R1

Ive just come back from a mammoth road trip to build a Fiesta R1 for a customer in Denmark.

I’ll do a full report tomorrow to show you the level we work at but for now here’s a very tired looking Jon Sharples of ShawSpeed fame and I after finishing it (95% of it anyway!)


Joe Nutter’s Focus RS Mk1

Joe’s car is coming in soon for some improvements and some finishing. 

We’re looking forward to working on it and putting our stamp on it, with proper attention to detail. Finishing off what Joe started and carrying on his own attention to detail will be a pleasure. 

We’re looking for close to 380bhp and a shed load of torque, so keep an eye out for it later in the show season!

You can follow our progress on here, Facebook and Instagram. 

For now, here are some photos!
