Round 5 of the 2015 ETS series was held at the beautiful "Ville de Luxembourg" track in Luxembourg. This track is famous for it’s "Lacuna Seca Corkscrew" with an amazing 2 meter elevation difference. This was also the track I took my first European Title back in 2009.

Thursday started with free practice in groups. With a total of 300 participants it was again a busy race with lots of racing in Formule 1, Stock and Modified touring car class. With lots of clouds and wind it was very cool but fortunate it stayed dry with good traction from the early stages of practice.

With practice under way it was Freddy posting good laptimes and soon I tried to copy more his setup to have a good starting setup.

First thing that was noticeable was raising the rear diff to its highest postion increased cornerspeed and the car became a lot faster in the sweeper on the end of the straight. Later in practice I played with different rollcenter postion and find out that anti dive was the way to go and made the car turn very nicely. On the end of day one it was Freddy and I posting top 10 times with Andy struggling a bit but not far behind.

On Friday two more free practice heats were scheduled with two controlled rounds to use those for the reseeding. Unfortunately it started raining so one free practice had to be cancelled. I ended up qualified 7th for the A group qualifier with Freddy in 9th and Andy overall 12th. In the first qualifier I was be able to run a 7th overall time, car felt very good with the race tires but some minor driver error prevented to be seeded higher. I had good hopes for Saturday as the car felt better and better.

On Saturday three more rounds of qualifying were scheduled and with more wind and a lot cooler conditions it was far from good conditions. In the second round of qualification I was battling with Ronald Volker for the TQ and I missed it by less then 4 tens, at that moment I ran the second run on the tires and it was clear that “used tires” could be same speed or even faster then new tires. This gave me already an A-main spot but of course I felt now there was a lot more potential then that. The third round I decided to run again with the old tires to save a fresh set for the last round. I had a good pace with a third for that round. Final round I decide to run fresh to have in my mind I could use them tomorrow in the mains, after some good runs with 2e run tires. On the end of qualifying I ended up third behind Volker and Hagberg.

Sunday triple mains were scheduled and all A-main driver could run fresh tires each final. However I decided to run my set of the last qualification and it paid off by taking a solid win while other struggle a bit with traction my car was glued to the track and I could easily overtake the two cars in front of my before the second lap.

For the second final I decided to run new tires to have again a set broken-in for the third final. But even now I was very competitive and I was fighting with Ronald and Bruno for the lead. After 4 minutes into the run I decided to push harder to try to overtake Ronald and I managed to get the inside line going up into the Corkscrew but unfortunate I rolled the car in the next corner by taking the curb a mm too close. This resulted in a fourth position for the second final.

So going into the third main there was still 4 drivers with a change of winning. Again I had a great start by overtaking Hagberg in the first corner and Ronald in the second lap. However I got too excited when I got the inside by Ronald and again I rolled it . I ended up on the roof with no marshall close so I lost a lot of time. While setting the fastest laps of the race in the third final I wasn’t be able to catch the leaders anymore and I had to settle with an third place overall while Bruno took the overall win with Rheinard in second.

Overall it was a great weekend for HB to finally got back on the podium and we showed the potential of the car.

Next ETS is in 4 weeks, see you there!
