Example Setups:

Notes:
(1) It's best if all drivers can make sure they are connected before the Qualifying session as drivers on track during qualifying will not see
cars that join after they are on track until they go back to the garage.
(2) Please make sure you are fully aware of the SimRacing.org.uk Rules (https://www.simracing.org.uk/index.php?pid=7) especially the
rules about in-game chat messages.
(3) You will need to install Race Room Racing Experience from Steam, and have the Euro and American Track Packs for this series (And maybe another
non pack track occasionally)
(4) Please exercise caution when pitting as some tracks have a speed limit.

(5) Please follow the SROUK guidelines for using kerbs etc. Please keep 2 wheels on the track surface (kerbs do not count as track surface)
Excessive cutting of corners will seen as cheating and the results may be altered to reflect this.

Anyone else tried this car and having severe difficulties keeping the rear from stepping out when locking the brakes? Even with 65-35 brake bias, I am spinning like a top as soon as the brakes lock. That's as far it lets me go so I'm kind of out of ideas how exactly this car is supposed to be made driveable.

You are probably driving harder than I am, and, I tend to come off the brake during downshifts
But have a go with this? For me it mostly locks the fronts if I just stand on the brakes.
Try reducing the brake amount event less perhaps?

Can you change the diff settings on the car? Increasing coast locking.

No diff is set except for preload.

Turning brake pressure down to around 85% seemed to help with bias at 57/43. Also changing down too quick is not recommended I found, don't think this car has a system which prevents changing down if revs are too high, hence it can lock the rears if you drop a gear too quick. Taking the hairpin in 2nd also seems advisable. Apart from the hairpin the rest of the lap is not too difficult.

Downshifting makes no difference. Try driving in a straight line, apply full brakes from 200 kph with no down shifting. The car will spin randomly to either left or right once the brakes lock. This is with 80% brake pressure and 65-35 bias. This is not how a race car is supposed to behave.

I find it to be a bit too much rear bias as standard. If everyone has the same issue
I can move to the 2003 variant, it's brakes seem more "normal"

Interestingly, if you return brake pressure to 100% the front brakes lock properly and the car stops in a straight line. So I suspect there is a bug where the brake pressure adjustment only applies to front brakes, not rear brakes.

 ??? Pffff, even more difficult than FRJ. Braking and throttling like its a brand new car.

Thx for the heads up, only thursday training would have been a disaster.

Confirmed on the S3 forum that they suspect it's an issue with engine braking. We can try and see how it goes on Thursday, but if the car remains broken I'm probably not going to do too many of these.

I would favour a change to using the 2003 car.

We have used the 2003 car before with no issues, and, I had a go at the same track, and I had no trouble with braking.
Shout up guys, otherwise I will change it to 2003 car tommorow.

The C-Class 2003 seems more manageable so I would favour switching, but also understand if people don't want to change cars so late. I think we need to make the decision tonight so people have time to prepare.

Post by: phspok on September 15, 2020, 04:37:03 PM +0100
I agree. I think I prefer the 2003 anyway, so amy happy to use that one.
Assume we will switch unless people shout this evening.

Personally I'd rather go with whatever came next in the poll if we're ditching the 2005 car. Had enough of DTM Mercs recently..!

I sense some vote swapping here  ::)

I am not doing NSU this series, we have flogged those to death. Next would be the Pork gt3 cup
which again we have done in the past and got some hate mail for. Yes I know some cars have
changed.

I am going to go with Merc2003 this time round, we will have another vote at the end for next series
if people want NSU we will do them. And anything else that is suggested will be in the vote

Restarted server.
Please note: For those that missed it, we are using the Merc DTM 2003 this series now.

Enjoyed that  ;D Lots of dicing, too much time in the sand which makes the tyres silly in this
like overheated tyres in AC are just nuts. Good fun all the same.

Well done Geoff on the win (and no mistakes?), well done Mark on second and strong pace throughout and well done Pete for battling back to third. Well done everyone else who raced as well for keeping it on the track better than I managed  :thumbup1:

This was the first time I'd ever driven these cars and every time I put a rear wheel onto a kerb in the dirty air behind another car it switched ends. Early on my pace wasn't too bad but every time I got closer to Mark I'd hang a rear wheel out onto a kerb and throw it off. As I lost positions and tried to play catch up, I'd throw it off again every time I'd closer to the next car.

My many excursions across the grass set up a good last lap battle with Toni, I was a little worried about throwing it off again and ruining Toni's race but managed to send it through the last two right handers and get the pass done cleanly.

My first time driving these last night, I know because when I came to join the server I had to buy one! Unlike Glenn I found I could lose the back on the kerbs without having to follow anyone  ::)

Got a poor start but everyone gave everyone room at the start I somehow I ended up third coming out of the hairpin out the back. Mark, Glenn and myself pulled away slowly but without mistakes I don't think I'd have got passed either of them. Then Glenn had the first of his misdemeanours and I was 2nd for all of about 3 corners and totally missed my braking for the right hander in to the stadium complex towards the end of the lap. Didn't mean to block whoever I did but the car was on jelly with the dirty tyres and I had little control.

From them on it was battling back. Made a couple of passes, got a couple of places as others had issues, and ended up in third. Probably where I should have been. These cars are going to be a handful elsewhere but I did enjoy my first adventure with them.

Bit late joining last night due to Windows update & then Logitech wanting to update GHub before it would recognise my wheel, so it was the start of qually by the time I got on the server. Qualified 5th, but I knew I could go a bit faster, so hoped to stay with the front guys in the race.

Early laps were not promising & after having a short dice with Toni I settled in to a steady race in 4th. A lap or so later this became 3rd when Glenn went mowing & a couple of corners later this turned into 2nd when Pete explored the gravel into the stadium. Glenn was still close behind & we were starting to gain on Mark but an error braking for the chicane let Glenn back past & lost me some ground. I regained 2nd when Glenn spun again & by now my lap times were really tumbling & when Mark got a bit squirrelly at T2-3 I was able to take the lead. Eventually managed to ease away & take the win. ;D

Congrats to Mark & Pete on the podium.  :clap: :clap:

The usual DTM story: good pace in quali, not so much in the race, especially once the fronts went. Had a strange event in the stadium section when Martin was making an overtaking move but avoided contact, yet my rear just came loose and I spun  ???. Normally I'd guess netcode issues but RaceRoom doesn't really have those. Is low-speed rear aero wash even a thing?

At least no more Hockenheim, the most miserable of all RaceRoom tracks...

Couldn’t get my line until the race, set my fastest lap in the race! ;D Then took too much kerb/accerator, my car did right angle turn and crashed at speed into the barrier.  ::)
