All Activity

Too late the algorithms have already captured you 😆

I've watched all the Terminator films, I ain't going nowhere near it dude! 😂

Anybody use this? I’ve been having a butchers and it’s a powerful machine!

@ Naranja_Al has a topic going in the tech section

Was a really good evening and didn't even have a Scrooby Doo of how the track flowed as did no pre watching videos so was a great learning curve! Interesting watching fellow cars scampa away into the distance as was pushing my road tyres to the limit but to be fair they have seen 3 Track days and 4000 miles of road use so far so wear rate is minimal even if limited grip, but fun factor is massive. Can't wait to do some more next year with you guys!

Aim to pass the IVA and not 'wing it'. It would be a shame to fail on such a simple/avoidable item. If with modifications, you can demonstrate they meet the viewing angles, you should be fine. My tester commented at the start that he likes testing Westfields as if you build them to the manual with the factory provided items they generally pass.

Thanks everyone for your knowledge I will have to make a decision about what to go for when I get to that stage of my build.

They are, or were effectively higher up than on a Westfield, so not as masked by the front wheels.

Morning all. I have been in contact with a few roll cage manufacturers about getting a cage for my car and the possibility of getting something specially made. Someone else has been speaking to one of them recently and wondered if it was anyone on here. Could you get in touch, thanks.

Congratulations what a fantastic, and well deserved result!

Thats brilliant @3739Davis , congratulations! The Caterham 8 spokes look lovely on the car too 👍

I've read that too, but it would appear to variable depending on the App and the phone. When Ben and I did a comparison of laptimes on a tandem fast run. Racechrono running in my car logged a 1m51.88 and Ben following with the AIM Solo and an expensive Garmin watch logged a 1m51.79. We do notice that the AIM Solo registers slightly higher top speeds (which could be refresh rate) but it's within 1-2 mph. Given we were in 2 separate cars, and a tenth of a second at an average speed of circa 80mph for the lap equates to under 12 feet of distance, this seems a good correlation over the 2.5 miles. It's close enough for my purposes (a bit of friendly banter about our laptimes!) and the data can be exported to websites like Fastestlaps where it's interesting to see how the car compares. They added the MegaS2000 to the list of cars for me: https://fastestlaps.com/models/westfield-mega-s2000 I've not even tried to interface it with the GoPro as yet.....

congrats on win 🥉 👍

i passed iva with a set of indicator pods fitted on my mazda sdv with no issues at derby. he asked me where i got them from i said westfield. i suppose its just down to the discretion of the tester on the day but it was some years ago. also mk use an indicator setup on there cars in the same position but different design

@Hugh Trantergood to meet you last night. Take a look at the for sale add here, this fits your brief

But don’t Caterham have their indicators in the same location? Pretty sure someone on here passed IVA with this type of indicator but it did require some fudging to get through.

Unlikely as they don't meet the viewing angle requirements as per the IVA manual. I 'borrowed' a nose cone for IVA to avoid drilling my new nose.

Thanks, Rob — that’s really interesting. I’ve read that the GPS sampling rate on most (all?) smartphones (1 Hz, one sample per second) isn’t accurate enough for sports applications, and that a higher frequency is preferable. I’ve been looking into data logging for a while now. My Dash2Pro does log data, but I find the interface and extracting/using the data quite clunky. It’s excellent for live lap and sector times, but nowhere near as good as RaceChrono Pro seems to be for data logging. I was impressed with @Mole’s Race Technology cloud-based logger, but if I recall correctly it’s both expensive and tricky to set up. I’m also interested in how RaceChrono Pro interfaces with GoPro and Insta360 cameras.

No, you don't really need an external GPS with a decent phone in an open cockpit car. Here's some data of my new PB (1m50.5). Circuit map with min and max speeds. You can overlay a few parameters on the telematics trace but I use the following.... speed trace in blue, longitudinal g's (braking or acceleration) in green, lateral g's in pink. Below is the Craners down to the Old Hairpin... You can see down the Craners I'm hitting 105mph, lifting for Hollywood with 1.12 lateral g's at 95mph before accelerating back to 106mph. Then braking to 71mph (0.71g) for the Old Hairpin. Peak lateral g in the Old Hairpin is 1.84 as I'm accelerating through 77mph This next one is the straight through the Foggarty Esses. 116mph peak speed, braking at 0.85g. Lateral g in the left/right is 0.99g and then 1.60g before accelerating hard towards the hairpin up to about 105mph. Its interesting stuff... I noticed on previous visits I was often braking too early, releasing brake pressure before reapplying closer to the corner. As I've got more confident on the brakes I can now see a smoother longitudinal g trace.

A longshot i know but you don't have any spare golf mark 4 rear brake calipers by chance. All the Best Paul

Can anyone advise me if these were fitted to my new build Mazda SDV would it pass IVA? So that I can avoid holes in the nosecone if upgraded after IVA.

Do you use an external (Bluetooth?) GPS module like the Racebox Mini with the Racechrono app?

My first official recognition! A respectable 3rd Place at the 2025 Boeing - Renton car show (out of about 40-50 cars). I was bested by a 1982 Ferrari 308 GTB Quattrovalvole, and a well restored 1968 Dodge Coronet 440 6-pack. Given that competition, I was more than pleased with the Westfield's first showing. Lots of people stopped to look and ask questions, and everyone loved it. Some knew about Caterhams, but Westies are pretty rare around here. I lost track of how many times I had to unlatch the bonnet to give people a peek at the Duratec.

Thanks.. I have actually used an adhesive plus have bought a high power soldering iron tool so going to give that a go to be double sure

What size light did you settle on?
