Set-Up Guide - Belgian Grand Prix

Spa Francorchamps Set-up guide

 

1. Engine

An engine with a strong top end is needed. This is especially the case for the drag up Raidillon and the Kemmel Straight which follows because it runs slightly uphill all the way to turn five. Good horsepower is rewarded in many sections of a lap, due particularly to its undulating nature.

 

2. Brakes

There are not many braking demands so, as a result, the focus is on keeping the brakes warm to ensure immediate efficiency when they are required. There are three major braking areas - into the first corner, into the turn 5 chicane, and then into the former bus stop chicane. These sections also offer the principal overtaking opportunities.

 

3. Suspension

This is primarily a high speed circuit and there isn't much use of the kerbs, so the suspension is tailored to high-speed balance rather than low-speed travel.

 

4. Rear Wing

It's very much an aerodynamic efficiency circuit where you need a reasonable amount of downforce without too much detrimental drag. A similar amount of rear wing to Canada is run, which constitutes a medium downforce setting.

 

5. Tyres

Pirelli are taking the soft and medium tyre which could spice things up a little, as it is a circuit that places many demands on the tyres. Also, the weather in the Ardennes can be very variable, even over the course of one lap.

 

6. Front Wing

In contrast to lower speed tracks, comparably more front wing is used which helps diminish understeer in the high speed corners.

 

  • The start is uphill, meaning drivers must hold their cars on the brakes; making a smooth getaway is sometimes an issue.
  • Tight first corner which is frequently the scene of first lap fracas, leading into the downhill section. Heavy braking down to 60 kph.
  • Down Eau Rouge and into Raidillion with an extreme suspension compression as the relief changes from downhill to uphill. Good engine power required for the uphill drag.
  • Flat out into the start of the Kemmel Straight or the long drag down to Les Combes.
  • High speeds of 330 kph – one of the highest of the season – before braking down to 3rd gear and 140 kph for the right hander.
  • Rivage provides a challenge as it's a medium speed 180 degree corner, heading straight into turn 9; good balance and change of direction are required.
  • Pouhon is a high speed left-hander, with entry at nearly 300 kph.
  • Turn 14 is taken at 140 kph. Cars accelerate through Curve Paul Frere, which is taken 100 kph faster, leading into the flat-out turns 16 and 17.
  • High speed section needs good car balance and strong aerodynamic efficiency, Speeds of around 300 kph achieved.
  • Heavy braking into the chicane after a prolonged high speed section; brakes need to be ready instantly. Provides a good overtaking opportunity.

  • Lotus Model Collection

    I have a bit of a Lotus model and memorabilia collection that I inherited from my Father that really needs to be moved on. Does anyone have any suggestions or experience on the best way to deal with this?

    TRD Airbox for Elise

    Hi, Apologies if this has been answered recently - I've just joined and couldn't find anything in the search.   I've recently bought a 2018 Elise Sport 220 which I've been enjoying hugely. About the only thing I'd like to change is the sound, and I've read that a TRD airbox is a big improvement. The problem, of course, is I have also read they are no longer made and I can't find any in stock either. So does anyone have any suggestions: - where might I be able to find one?

    Evora 400 Audio Upgrade?

    Hi Guys It took me over a couple of hours to drive back from LiTP because of traffic etc. Its the first time I tried listening to the stereo and it was pretty dismal. I did some research and it turns out my car left the factory without the rear amp, subwoofer, cabling and brackets so I'm probably looking to install a mini amp, sub and upgrade the front speakers as apparently they are very poor. Just wondering if anyone else has done anything similar to their Evora and what they did. Wo

    Poster for the 2027 Lotus in the Peaks.

    As I’m sure many of you will be pleased to hear, the work has started for 2027 Lotus in the Peaks. Paul (Oakman) had a fantastic idea for next years poster, so today we banded a few cars together and went out to do the photo shot. I happened to leave my dashcam running.  Enjoy   Photoshoot.mp4
