There are sound engineering principles as to why the spoiler could both increase or decrease drag. However the interaction between every minute feature on the vehicle body is so complex that it's really not worth guessing either way without wind tunnel or CFD evidence. E.g. the rear of a car...

Yes, it's supposed to have rubber spring seats which A) reduce wear & noise by eliminating metal on metal contact and B) stop the spring falling out (lowering springs still aren't the most secure thing you've ever seen even with the rubber spring seats)

There isn't a conventional one as such that attaches to the spring seat on the damper, but there is supposed to be a rubber sleeve that wraps around the first one & a half coils to do the same job.

Soft compounds generate more heat per amount of force you put in AND the compound enters it's optimum range at a lower temperature. This means a soft tyre can be used in comparatively colder and damper track conditions than a harder compound until the tyre can no longer evaporate water. If...

Apparently we've been saying Yaris wrong for years as well... Yaw-wis...

Secret? It's one of the biggest and most well known Motorsport/Engineering/R&D centre in the industry :wink: But yes, anywhere with that much 80s/90s/00s motorsport heritage is brilliant.

I suspect you were just seeing "pickup" as A) it occurs on all types of tyre on tarmac & always clears up after more mileage and B) Although Martin Brundle uses the word every 5 seconds it is actually a very specific phenomenon that is quite rare on light low powered cars.

The rolling radius is not the same. The circumference is not even the same. Rubber stretches & changes shape under load. A completely flat tyre clearly has a much lower radius. Now extrapolate that to a "half flat" tyre, then 1.8 bar, 2.0 bar, 2.2 bar etc.

By EU law the speedo can not under read. It can over read, but only by a maximum of 10% + 4 KPH. http://www.unece.org/fileadmin/DAM/trans/main/wp29/wp29regs/r039r1e.pdf Of course this goes out the window somewhat when people fit different brand tyres, different size wheels, different inflation...

Are you buy any chance using lowering springs? Manufactures spend weeks tuning & tuning & tuning the suspension travels to be perfect, and then the numb nuts aftermarket goes and sticks on 40mm lowering springs (basically moving all of the damper's internal components either 40mm closer or...

Reaaallllyyyy simple :) Open glove box. Put fingers on the underside of the plastic strip. Try to pull the bottom out & up at the same time. No screws or anything. Driver's side is the same.

The "Renaultsport" logo on the 172 has yellow/blue/red stitching. The 182 has grey stitching.

My favourite part of that advert is "no more turbo lag." I didn't know the 172/182 had turbo lag...

Absolutely, I think they look & sound dreadful :smile: They don't even sound remotely like the type of noise a Group N let alone WRC Impreza (for good reason) makes either. The car in this thread though, is absolutely lovely.

Much prefer it to the usual over-sized baked bean can you see on old Imprezas though!

With a 5 sided socket of course... ;) http://www.ebay.co.uk/itm/10mm-14mm-19mm-PENTAGON-5-SIDED-BRAKE-IMPACT-SOCKET-SET-NEW-/390763823891?pt=LH_DefaultDomain_3&hash=item5afb56c313

What are you typing your forum posts on? Small stuff at home is very manageable these days on a surprisingly modest spec. Might be a case of finding some (old) compatible RAM on ebay, chucking it in & away you go.

I hope to be brief, because you could go on forever. To tailor a computer to CAD you'd want more cores rather than chasing outright processor speed & to be spending a much higher proportion of the budget on memory/HDD than GFX card compared to a gaming machine. A typical "good all round" £500...

ball park Servicing at SJM Automotive LTD.

Yeah the one across the road from Four Candles actually.

I think I owe Dave a Christmas card this year! I got ID'd in the Odeon a few weeks back xD

Still a bit fragile over here. I've remembered a few more bits that I found funny... Sash & Ali spending 5 minutes sweet talking a bouncer into letting us in to a club without paying entry, walking up 3000 flights of stairs to the top floor, Dave took a 3 second look said "nope, not for us"...

That's assuming the OP has camber bolts? I'm just being annoying tbh. If I hadn't had it tracked in a while and the top mounts were coming off/going back on again then it's a convenient time. I would want to drive it a few miles to let things settle though.

Don't know what anyone was planning for food buuuuutttt... There's a beefeater (or similar) attached to the hotel. Wondered if people fancied grabbing a burger or w/e there before finding a pub. It would perhaps be a good way for new faces (are there any?) to learn names/faces before Daniel etc...

The connector is the bonnet closure switch/sensor. See the identical coloured bit of plastic literally 5cm from the connector in the first pic? It's supposed to be part of that, but it clearly broken. Connector looks fine, but the switch seems to have disappeared leaving you with just the...

Worst* "I build P2 cars" thread ever? ;p *and first

Did you do a fresh install on the other laptop and be careful not to instantly install loads of crap? I realise it was a Celeron/Pentium something or other so never going to be lightening fast, a laptop HDD takes about 17ms to find a file (let alone load it), whereas the processor is doing...

Be thoughtful about it. Put a heater back in (just move it a little bit & use ducting surely? Put it on the floor for race car weight distribution if you like :p) but run a few lengths of small ducting to key areas rather than heating up empty space. Quite a few endurance cars at Le Man etc...

Great move with the SSD. You'll "feel" much more of a difference going from a 5400 RPM hard drive to a SSD than you would by spending an extra £2/3/400 on other components...

As above, there's much more than to suspension than "low & hard" and once you've designed everything (wishbones, steering arms, dampers etc) to be in a very sensible place (the car also has to get in/out of gravel car parks, speedbumps, be able to go up curbs etc) it generally makes lots of...
