E92 - TMS Aero & Bodywork Changes

by Thorney Motorsport - Wed, 03 Mar 2010 12:36

This month is a bit of a work in progress really as a race cars aerodynamics can only really be fine tuned and fettled whilst out on circuit (sadly we lack the £40m odd needed to run our own wind tunnel, although we do have access to one) so the initial stages of design are developed on the chassis in a static state. The very subject of aerodynamics tend to bring out the worst in people, everyone happily quotes drag coefficients, down force levels and anything else they’ve managed to learn from the internet usually losing sight of the one key feature that matters above all else – there is no one feature above all else – aerodynamics and bodywork design has to cater for so many requirements that there is no one single design that can do everything, you have to compromise.

E92 - TMS E92 M3 Roll Cage

by Thorney Motorsport - Mon, 11 Jan 2010 16:28

We seem to have more phone calls and questions on cages and their fitting than anything else these days, be them for full race car preparation or just track day use there does appear to be a lot of misunderstanding about what a cage is designed to do it seems.  In simple terms there are two kinds of cages for cars – a safety cage and a chassis cage. A safety cage is exactly as it sounds, a cage installed into the car to protect the occupants in the event of a crash, its purpose is simply to prevent the occupants getting squashed in the event of a side impact or worse still a roll over. Pretty much all bolt in cages are safety cages...

E92 - Strip Down

by Thorney Motorsport - Tue, 08 Dec 2009 11:54

Its not been a bad development for the E92 M3, over the last 9 months we’ve upgraded the suspension, wheels, brakes, exhaust and power nicely so overall we’re pretty pleased with the development thus far. There have been some notable highs, such as a spirited drive from Cornwall to Milton Keynes in the early hours which demonstrated the Moton suspension and AP brakes to their finest as well as countless times where the roar of the Akrapovic exhaust simply made us smile just for being in the car. Hearing the Safety Car Drivers of the CSL Cup describe the car as the ‘best safety car they’ve ever driven’ was nice as well as well as comments from owners saying that at last they thought the car looked good also stand out.

E92 - BMW M3 Performance Seats

by Thorney Motorsport - Mon, 07 Dec 2009 07:30

E92_Seats_001.jpg
Original seats.
The observant readers will have noticed that this month we have cheated, either that or we’ve re-sprayed our black M3 white for effect and that’s not very likely. The reason for this less than subtle vehicle change for this months instalment is that we have been planning an upgrade to the seating for some time but as our own car will soon be entering its race car preparation phase there was little point in spending a lot of time upgrading the standard seats as they would soon be ripped out anyway. So step forward Tony Rodriguez and his own E92 M3. Some of you will remember Tony from previous issues, he’s already taken a couple of E46 M3’s to new territory in racing but now he’s moved up to the E92 and he contacted us for suggestions as to what we thought for upgrades.

E92 - Suspension Modifications

by John Thorne - Thu, 01 Oct 2009 08:00

Well thank God for that, we’ve finally managed to fix the E92 M3’s biggest problem – handling. Now I’ve been fairly critical of the E92’s handling in general, indeed the standard car on standard suspension I think is just way too soft for a sports car that the M3 represents but it does reflect BMW’s seeming intention to re-classify the car as more of a GT car. For me, if I wanted a mile munching BMW GT car I’d get an M6, for me the M3 represents the hard edge sporting end of the M range and the M3, on standard suspension just doesn’t cut it...

E92 - Akrapovic Exhaust System

by John Thorne - Wed, 26 Aug 2009 17:04

A lot of people ask me how Thorney Motorsport started and how I got into car tuning and as with a lot of people in this industry my story is pretty similar; mad keen on cars, modified and tuned my own cars then friends cars, then set up on my own, all pretty typical. However where I think Thorney Motorsport and myself are a typical is what we think of the tuning industry generally, in short its crap..

E92 - AP Racing Brake Kit Upgrade

by John Thorne - Wed, 12 Aug 2009 11:32

We love BMW; they create some of the greatest drivers cars on the planet. Cleverly styled, impressively engineered, expertly marketed and perfectly packaged as the ultimate drivers machine. So why on Earth can’t they provide an M sport car with a decent set of brakes? I shouldn’t complain of course, without BMW fumbling the ball on brake set ups on M3’s then companies like Thorney Motorsport might not be as successful...

E92 - Pads & Springs

by John Thorne - Wed, 12 Aug 2009 10:53

It's a different month this month, thus far we’ve covered cat back exhausts and detailing and the plan this month was to cover some aspects of brakes or suspension in detail but we’ve only gone some way in both these areas so we thought we’d cover them this month by introducing the cars other role as the CSL Cup Safety Car.

E92 - Exhaust & Dyno

by John Thorne - Tue, 12 May 2009 14:30

I do have huge sympathy for car designers, they must develop and deliver product to an ever widening customer type and attempt to supply the impossible to very demanding owners. However just because I understand the difficulties they face does not mean I’m not unhappy with the obvious shortcomings of the product...

E92 - The Detail!

by John Thorne - Tue, 24 Mar 2009 10:00

The car was suffering from low levels of gloss and was covered in swirl marks when the sun shone on it. So first things first, I called Mike and Martin from Crystal Clear Detailing to come and perform a ‘CC Ultimate’ detail.
