Great video, one thing I might say is make sure the car you plan on using will meet regs. Seen a few people on social media wanting to get into road and targa rallying with 6 cylinder BMWs which won't be permitted.
Great point! It would be nice if Motorsport UK did a quick "dos and don'ts" list for different forms of motorsport, so people can at least get an overview of some of the regulations before diving into the minefield that is the blue book
Brilliant video. One I'd add is 'keep it simple'. I fitted a cheap digital dash, because it looked sexy. 😂 I had no end of trouble wiring it in and it offered nothing that the standard dashboard didn't do already. It was a total waste of time and money and was just another thing to go wrong.
Totally. I ditched the standard cluster in the Escort because the Focus gearbox used an electronic speedo instead of a cable one. It was nice having the little rev counter etc, but it added extra work. Far better to keep as many of the standard electronics as possible if you can!
Some tips to weight reduction: Shorten the bolts need not to stick out of the nut Use alloy washers Use alloy nuts and bolts at places with no stress (front wings etc) Cut wires out with no use (rear wiper etc)
@dimprian0077 Any car competing in the WRC has to be homologated by the FIA into one of the five eligible categories; Rally1, Rally2, Rally3, Rally4, Rally5. That said, only Rally1, Rally2 and Rally3 have classes to score points now. The regulations for each class are way too long to post here really, but this is a rough guide: - Rally1 (as of 2025): 1.6-litre, turbocharged, 35mm restrictor, 4WD, five-speed sequential gearbox, minimum weight of 1,180kg, based on an FIA-designed spaceframe chassis with scaled composite body work based on a production car - Rally2: 1.6-litre, turbocharged, 32mm restrictor, 4WD, five-speed sequential gearbox, minimum weight of 1,230kg, based on an FIA-homologated production car at least 2,500 units built) - Rally3: Up to 2,000cc normally aspirated or up to 1,620cc turbocharged, 30/31mm restrictor, 4WD, five-speed sequential gearbox, minimum weight of 1,210kg, based on an FIA-homologated production car - Rally4: Up to 2,000cc normally aspirated or up to 1,333cc turbocharged, 30/31mm restrictor, 2WD, five-speed sequential gearbox, minimum weight of 1,080kg, based on an FIA-homologated production car - Rally5: Up to 1,600cc normally aspirated or up to 1,333cc turbocharged, 30/31mm restrictor, 2WD, five-speed sequential gearbox, minimum weight of 1,080kg, based on an FIA-homologated production car
@dimprian0077 No it has to be a specifically homologated car. Basically, when a manufacturer homologates a car, it is eligible for 10 years. After that, you can no longer use it on WRC events (unless that individual rally has a "national" section for non-homologated cars). Right now, only the manufacturer can homologate a car into Rally1, Rally2, Rally3 and Rally4. Smaller companies can homologate cars into Rally5 using the "Rally5-kit" rules which came out this year. That's to try and create more affordable entry-level cars, as Rally5 cars are pretty close to standard
Good suggestion, but I guess not always necessary for people that only want to compete at grassroots level. It can make life much easier though, as if a car has been built to Group N/A spec in the past, there will be knowledge and parts out there
Really good video as usual. Your response to aluminium door cards was a lot more polite than mine 🤣 I would add aswell try not to build a WRC car. What I mean by that is keep it simple and low spec to start with and just get out there and do some events !!!

Some really good suggestions there! When I built the Escort, I became obsessed with aluminium bolts 😆
Hahaha, can save up to 40Kgs
Great video, really interesting!
@@SMAC364 thank you, really glad you enjoyed it 😎
love the attention to details & examples!
@@balthazarvanovermeire912 thank you, really glad you enjoyed it!
This came just at the right time !
@dimprian0077 I'm glad! I hope some of it is helpful 😃
@maximumattackrallying just one 1question, do you know the specifications to race a car in the WRC ? (Power/weight, safety measures etc.)

- Rally3: Up to 2,000cc normally aspirated or up to 1,620cc turbocharged, 30/31mm restrictor, 4WD, five-speed sequential gearbox, minimum weight of 1,210kg, based on an FIA-homologated production car
- Rally4: Up to 2,000cc normally aspirated or up to 1,333cc turbocharged, 30/31mm restrictor, 2WD, five-speed sequential gearbox, minimum weight of 1,080kg, based on an FIA-homologated production car

@maximumattackrallying so, can I build a Rally 2 homologated 4wd Ford Sierra Sapphire or is it a specific chassis that can compete ?
@dimprian0077 No it has to be a specifically homologated car. Basically, when a manufacturer homologates a car, it is eligible for 10 years.

Fun video
@@MrHordeman thank you!
pick something thats homologated
