Jardo, look into a master cylinder brake stopper if they're available for your car. Bolts to the strut tower/something solid and sits against the back of your master cylinder and prevents it being flexed forwards into the belt when you brake. Improves pedal feel further too!

99% of the ones ive seen mount right at the end of the master cyclinder, so it's be no use in his case.

guess you'd mean more this design?

Highlights vid from this weekend...

That was a thrilling watch Adam, especially 2:48 and onwards. Well held, nicely avoided and well held on the grass too :D Looks like such an enjoyable and skillful racing series. What tyres do you run in the wet, NS2's? Do you have ABS?

Also intriguing lines in some places but they seem to work better than your competition. I'd love to see a g-meter in your vids one day. What kind of G's do you think you're hitting and what's that box in the middle of your dash?

Mx5 people (Tarty Adam) I need your help.

On the way to work this morning my mk1 eunos ran a bit rough at idle at times and twice I felt a bit of hesitance when accelerating away.

Any pointers? I've not had chance to have a look at anything yet. It's been hammering it down if that could cause issue.

Does your idle go up and down when it's cold?

Try a diagnostics tool on it, but if it's anything like mine it's just the idle control valve either needing cleaning or replacing.

There's a few things it could be though, so get it on the diagnostics and see what code you get.

Cheers dude, same for your vids! Haha, yeah there were a few hairy moments, keeps you on your toes though :) The level of driving does seem good yeah - for example a guy who won Formula BMW in his first season, got onto the Red Bull academy, won 14 out of 16 races in another series in 2012 (his first season racing that car) and nearly won the MX-5 Mk3 championship last year qualified 16th, DNFd the first race (span into the gravel) and was 25th in Race 2.

The control tyre this year is the Nankang NS-20, it's a budget Chinese road tyre, about £35 each over here. If ABS was fitted to the cars as standard (rare), it must be removed to comply with the regs.

Yeah, I tend to spend quite a lot of time playing about in the wet to try and find where the grip is, the regular lines get so polished up they are like ice, so by taking outside lines and braking about a car's width inside where you normally would you can often find more grip. You travel a bit further but the key with such little power is keeping the car rolling...

The box is my datalogger - I'm pulling about max 1.3g lateral / 1.0g braking in the dry and max 0.95g lat / 0.75g braking in the wet. The fact I barely ever seem to lock the brakes means I'm not trying hard enough though :lol:

Cheers for the help folks, I'll try an Italian tune up on my way home and then lift the bonnet see what I can find. It did it when car was warned up. I have a theory it could be that I had heaters on full in idling traffic so battery may have discharged slightly.

Do those sorts of things really make a difference? Looks like a quick little project that'll cost naff all if so :D

Makes a massive difference in my old mans hill climb car. It's fitted with a Cusco master cylinder brace that fits under the front strut brace on the drivers strut tower. Without it you can watch the BH flex 5-10mm, with it its rock solid.

Wow, that's a lot, I was convinced it'd be in the region of 0.95 in the dry. Amazing performance from those tyres then. I've pulled a maximum of 1.25g lateral on WTCC slicks, probably because of the weight. How much does the MX5 weigh?

What you say about the difficulty seems to be common - amateur events appear to often have better drivers than the semi-pro stuff like GT3. At the end of the day, the difference between pro and amateur is mostly the budget you have at your disposal.

It's more the chassis I think. The camber correction of the wishbones is amazing. Soft suspension works well in some cases ;) The MX5 is 960kg with driver, and we're on 195 section tyres.

Makes sense and I would agree. Prime example right here at the front of our grid. Check out how the red and white car gets a crap start then somehow is in front into turn 1! That's just a plain power difference...

Not heard this italian tune up before? After a quick google is it basically driving your car on the rev limiter for x amount of miles?

Yup, works absolute wonders for diesels too as when the cylinders get hot enough it burns all the crap off the injector heads that's built up over time from driving like a vagina.

Best turn my music up then, driving in high revs in a diesel sounds horrible, let alone staying there....
