    Short update to my build thread, its been a while since I've done anything with the Clio, after the last round of light weighting, I have a steering fault that means it needs to be recalibrated, I can either buy a clip tool, or wait for the RStuner update that will let me do this, and as I don't...

    GW 200 CUP (clubsport->racecar->v2)

    have a bit more time to reply so I looked back at the last set of runs I did that led me to remove the diffuser. I've posted previously on this forum about how the diffuser does work, and you can show it, but the effect is small because the diffuser volume is small, and being so small, the 197...

    GW 200 CUP (clubsport->racecar->v2)

    Yeah I use openfoam, easiest thing to do is take a copy of the motorbike tutorial and alter things like the frontal area and centre, speed etc, then swap out the geometry for your own. I don’t have a machine setup to run it currently but should have a backup of either the files or the Ubuntu...

    GW 200 CUP (clubsport->racecar->v2)

    interested in your results with that style of drag wing. this was my preferred style of wing from the CFD I did a while back, does depend what your trying to achieve though. If my memory is correct, then it will certainly reduce drag, it will also decrease the effect of the diffuser if you use...

    UltraRed 200 FF CUP - Weekend warrior

    I agree with RSRowe here, roll bar preload occurs when the cars sat at its static ride height, but different length links on either side mean the bar ends up with force applied whilst the car is static. There is some good videos about how to fit adjustable length links to avoid creating preload...

    mix of reasons really, its generally cheaper to get a lightweight wheel in a 16 for example I have a set of JR3's in 16 x7, they weigh 6.6kg each but cost me only £130 a corner, getting a 17 inch wheel that weighs similar is generally over twice the price. I can run a 205/45/R16, so the tyre is...

    Was doing a little fettling today so took some pics of things I didnt when rushing to get it back together. Inside of the front bumper, haven't had any issues so far with this and it feels really light compared to standard, The radiator support has been replaced with a bit of box section...

    Great chance today to contribute to good causes and get a shakedown of the latest changes at Golspie track n show at the sprint circuit there. Met up with another few Renaultsport owners which was cool one of which kindly sent me this picture. It was a really well run event with hour long...

    few more pics of changes, the front bumper weighs a lot stock, which is weight hanging out Infront of the front tyres, so all the plastics in the large mouth area are gone, and i've trimmed the bumper a bit, replaced with some mesh, and some abs sheet to reduce the size of the opening, quite...

    With 1121 as the starting point when it was last weighed with around 17-20kg of fuel (was showing half a tank. My notes aren't great but the main things I've done to reduce weight are: 1. Dashboard stripped to a single skin and remove plastics around the steering column, around 6.5kg 2. Rear...

    Zubans LY RS200

    Yeah no probs I’ll do a post tonight when I can get to my pc and notes. I made a choice not to cut into the body or go fibreglass etc, partly on cost and mostly on making sure I had covered all other options before resorting to that. The engine is stock internally but with a lighter flywheel...

    I haven’t cut any of the metal inside other than the unused brackets, there still a couple to come out which are those above the fuel tank. When I had it weighed before at 1121 I still had things like full dashboard and a passenger seat. Lots of little things have been done, I’ve kept notes of...

    Been six months or there about, not much done over winter whilst my wife got her business up and running, but motivated by a potential shot on the nearest sprint circuit this weekend I got set in to get the latest round of changes complete. I've been chipping away at it over the last few weeks...

    looks great did you re-use any of the existing heater wiring or just tap in to the power and ground fresh with a switch?

    The clio is off the road whilst the brake calipers are sent off to be rebuilt, so i'm cracking on with some other jobs, one of which may be of interest to others. I had originally intended to use an arduino to get canbus info and display it on a small display, but when thinking about it...
