I look after the Renaultsport road car activities for the UK. I've been with Renault for over 10 years and have been in the industry for 25 years (gulp..). We hold regular trackdays, factory visits and events where all Renaultsport owners can get together and where there's a range of cars to try. I look forward to seeing you at the next one.

Dear Allen Collen, I am a student who has a huge interest in Formula 1 and therefore I have decided to start a project essay on the aspect of race strategy. I was wondering what your views are when it comes to the differences between the drivers’ ability with their respective F1 team cars and how this impacts the race strategy. Also how do you make changes to your strategies when certain variables take into effect such as weather, car collisions or human errors? If you know of any other contacts that can provide further information on these topics that would be very useful. Thank you for reading this and I will greatly appreciate any help that you can offer. Many Thanks, Joinul Haye

Dear Joinul, Thanks for your note. In deciding strategy, there are a number of variables but the drivers task/job/requirement is to be as close to 100% efficient for the performance potential of the car. This includes minimal loses when lapping back-markers, managing tyre performance to extract the maximum from the car. f they cannot complete this they fall short. Weather and other on track incidents create opportunities to adapt or change strategies but the start point should be optimum car performance. Best wishes,

Hi -- so I'm trying to change the tyre brand from Michelins to either Continental or Uniroyal. The problem I have is that it's uneconomical for me to change all 4 at the moment and since the fronts have worn out first, I'm in a dilemma of going for continental sport contact 5 tyres which have the same tread pattern as the michelins, or going with Uniroyal Rainsport 3, which is the tyre I want however has a different tread pattern. What would be an answer to this dilemma? Thanks

Ideally tyres should be changed as a set of 4. If for whatever reasons this is not possible, changing in axle sets is the next best solution. Regarding the tyres mentioned i'd prefer the Michelin's or Continentals as they OE suppliers.

Hi, Sorry to hear of your issue. However all components are subjected to prudent design and testing criteria before being installed on mass produced cars. The testing process has to be in different temperature extremes, duty cycles combined with a variety of different users and driving styles. Kind regards,

Hi, I have a Clio 182 with the cup pack option, and for a while I have fited some aftermarket wheels with slightly different offset (ET37 vs the standard ET45). This change the track width but also the scrub radius and I want to kow if this is something to worry about or not. Also, any idea what the standard scrub radius is on my car? couldn't find this data anywhere so far. And just for curiosity, what's the scrub values on the clio 172/182 race cars? Many thanks! Best regards, Razvan C

Hi, Any deviation from the OE settings will have an impact on tyre wear and overall performance. The race cars have similar but specific suspension to cope with slick tyres and influence dynamics. Kind regards,

I cannot extinguish the lights on my 2012 RS200 MSK.3. The battery is now dead and I cannot even get into the car to release the bonnet for charging. Any suggestions?

Hey Mate, How are you? Hope all is well. Currently I have owned a 2014 Renault Clio RS200 EDC. I wanted to ask about my front brake, is it made by ATE or TRW? Thanks, Freddie.

Hello. I have 2005 Renault Sport Megane 225. Its the standard model. Can you advise me where i can get an ECU wiring diagram to go through the wiring? I am so desperate to find this fault. Today i collected it back from Mitchells Renault garage and they are baffled whats going on. Basic story is the car goes into Limp mode with check injection and engine management light coming up, on the computer saying throttle body fault but everything has been replaced, new throttle body etc etc, new battery and I've even sent off the ECU to get checked, everything is fine so last call is the wiring. Please advise where i can purchase or download the wiring, many thanks.

Mitchells can access the wiring diagram
