They are AP Racing 5000R+ so calipers are OK but discs and pads probably require changing.

They're more than glazed, rough them up and they glaze up again immediately. Think new pads and discs are on the agenda.

It was just a matter of adjusting the coilovers until it stopped hitting the bump stops . The brake pads are not wearing down at all, neither are the discs so something is definitely wrong. It could be the friction material has been baked so often and is too old to be effective but not something I've come across before. They'll slow the car down but at the expense of having to brake earlier than you'd like and the heat build up in the calipers can then be a problem. Obvious answer is new pads, discs, or perhaps a big brake kit, and a valve to set front/rear brake balance would help a lot.

Japfest Donnington last Saturday, split screen vid of the MR2 and S/C Celica (two cars featured in Banzai Magazine July edition). Celica top screen MR2 lower. Tried running the MR2 without the temporary Vee silencers but got pulled off for being too loud so clamped back on for this session. - Cubic capacity versus supercharged - Torque versus BHP ? - RWD versus FWD https://youtu.be/ol2Yx_nZbMA

Not decided but as the new one is definitely not fit for purpose it needs to be rectified so it'll be up to Rogue. If the car fails noise tests at Donnington tomorrow he'll have to run with those clamp ons (which one of the Infinity Exhaust guys managed to fabricate at Castle Combe). Testing at Combe was static whereas Donny is drive by so with any luck it'll scrape through with have to use them. He's back on the learning curve with the extra power, but having to brake a bit earlier because of a lack of confidence in the brakes. Even so the passenger experience with the 'G' force is a bit horrific, my crash hat is taking a beating on the roll cage!

Remap helped but real issue was restrictive intake so put a larger. Intake with a bigger filter and bhp shot up on the dyno by almost 50 bhp. Track day at Combe today but static noise check was 102 dB so not allowed on track. Rigged a temporary fix and managed two sessions which were absolutely manic, faster lap times than he’d done before. However, slowing the thing down is now a problem as the current setup can’t cope...development never stops I guess. Donnington this weekend so silencer and brake improvements will have to wait

Here's the comparison of the original (top one) and the newly modified relieving the stress points. We need to keep the shafts as weak link in the drive chain to protect clutch/gearbox etc. which would be more expensive to replace in time and money, especially as it's heading to Surrey this afternoon for a remap as it's always been set up slightly de-tuned as a 24 hour endurance racer. To help with the bhp improvements Rogue has custom-built a twin pipe exhaust system in stainless steel, which given the limited space is a work of art. However although it's quiet enough to hold a decent conversation at motorway cruising speed, it's absolutely deafening when the foot goes to the floor so will need to find a way to sort that as I'm sure that at most tracks it'll be a problem passing the noise tests.

They had to be modified to fit the V6 installation. Advised Rogue on not repeating the stress raisers but they had already worked that out and machined a new pair of shafts accordingly.

The shafts were modified MR2 Turbo ones. Unfortunately Rogue machined sharp corners instead of radii so there was a stress point, just fortunate it held on the drive back home from Santa Pod..failed completely a few hundred yards from home. XILX3335.MP4

Well I did tell him not to put a circuit car on a drag strip.....completely sheared a driveshaft like snapping a carrot. OK the car doesn't weigh much but holding high revs and dropping the clutch from a standstill with R888 sticky tyres will definitely test the complete drivechain. Just fortunate the weak link was only the shaft. LVEB5740.MP4

Why put a circuit car on a drag strip? Just doesn't make sense. It's all about BHP and getting that power down so the outcome of going up against a car with a lot more BHP over 1/4 mile is fairly predicable. OK the power to weight ratio will make a difference and no doubt that GTR would lose out on the circuit and as for doing it again against a 'lesser' opponent well again what's the point?

Bit unnecessary though, not a lot of skill in running a track car in a straight line just extra wear and tear on the running gear. Had a few words

Don't know why he thought taking on a 500-600 bhp GTR was a good idea though ...David and Goliath springs to mind. WNXY9392.MP4

Give the edge a clout with a lump hammer, if they're copies most likely will fracture, BBS forgings will just distort. Fair bet they're cast replicas of the original forged and heat treated rims looking at those pics.

He took it to a show at Santa Pod today but he said it was just a car meet so wouldn't put it on the strip... yea right. Just sent me a copy of of his three runs.. Only 0.2 seconds slower than a 310bhp MR2 turbo in a straight line, probably because of the extra torque. Hate to think what the car will do when it's correctly mapped and charged. Better sort out the suspension niggles then
