Me and my new suspension following a GT3RS

Great video!

Any other mods on your car?

AP racing brakes with pagid pads, BMW stutbrace, CSL wheels with Michelin Supersports...and from last week the PSS-10 suspension. No engine mods, no weight los...
 
Cheers for sharing again! Impressed at the Zed's performance on the straights, I thought the porka would really pull away stronger than it did!

Great video ! I'm going to the ring in July and I've been learning the track on my PC using a game called Project CARS (website for anyone interested - http://www.projectcarsgame.com/media.html)
and I was amazed by:

(a) How similar the virtual track is to the actual track.

(b) How much of the track I've managed to memorise !

Track didn't seem too busy, was this a mid-week evening session ?

I've not played Project CARS yet, but if it's like most other games with the 'Ring on, then they're fine for showing which way the track goes, but not so good at showing you where the little crests, kinks, bumps, etc. are.

You probably won't notice the little things at 5/10ths if you're careful, but at higher speeds, or where you've got yo go 'off line' to get around traffic, then you can easily be caught out.

I decided to use a book (a Circuit Guides one) to learn the track, and just built on that corner by corner, lap by lap. After about 400 laps, I still don't get them all right - nor does my mate with over 5000 laps under his belt (courtesy of his days working at the Ring for Aston Martin & Cosworth).
 
Franzino, your car looks as though it now drives nice and "flat". How did you like your Bilstein suspension and what settings did you find the best?

Before I went to The Ring the first time, I used GTR2 on a PC and I found it a great way to learn the track layout so when I drove it, I knew exactly where I was and didn't get disoriented or lost. However, the one thing that GTR2 didn't convey was the gradients at The Ring, which is what makes it such a fantastic place to drive.

The later GTR Evolution is even better and has even better "Physics" at The Ring. I'll take a look at Project Cars.

I've always suggested that the rear suspension on the Z4M should be softer than the front for 2 reasons. 1. since you sit almost over the rear axle, the rear suspension settings determine the ride you perceive and 2. softer suspension on the driven wheels gives better traction.

For me, the problem with the OEM suspension is that the rear suspension is too stiff and the front is too soft, by fitting aftermarket adjustable suspension you can get a better suspension balance.

Correct; you suggested this set-up (softer rear) to me in older PM and it sounded logic. With a softer suspension setting at the rear, you normally have a little more understeer at the limit (which is a little safer to have a warning that front starts to slide). Last sunday it was my first track day (Nurburgring) and the second day with my Bilstein PSS-10. I experimented with equal settings (5/5), softer rear (5/4), softer front (5/6)… I did not feel completely confident and satisfied with settings 5/4 and 5/6…on track. I then switched to 5/5 and it felt more stable and more secure to me. The balance was better…but in some corners I stall had a little bit to much body movement, so I switched to 6/6 and this felt rather good. The harder the suspension, the lower the grip is the rule…but this setting felt good and I did not feel the need to go harder then 6. I wanted to try 6/5 and see what a little softer rear would do at the track. But that would be for the next time. The Nurburgring is a really bumpy track and it's not a good idea to put the suspension to hard… 6 (4 knobs down from the hardest setting) felt really nice.

What I did notice is that my TC light started to flash more often in certain corners. Maybe this is because I took certain corners faster then before… It was only a slight flash (without cutting power). I will do more test when I'm there again; but in first opinion I think the numbers for street driven will be around 4 (also in wet), for the Nurburgring (dry) around 6 en for Spa-Francorchamps (dry) somewhere in the area about 8 (2 knobs under the hardest setting).

If only the horrible noise from the suspension can be fixed, then I would be completely happy… http://www.z4-forum.com/forum/viewtopic.php?f=9&t=66166
Going back to my shop to get this sorted out.
 
clubsport as 20 clicks of adjustment

i run 6 clicks rebound, 4 clicks compression front
12 clicks rebound and around 6 clicks compression rear. These are KW recommended fast road / track settings, the dedicated track settings feel too stiff on the road.... I've tried a few different settings now and kws own recommended fast road / track settings feel pretty god damn good...

I'm glad you're enjoying the suspension! :thumbsup:

The actual numbers that you choose to set your suspension dampers don't matter at all. What does matter is that you can find settings which give you the handling (and ride) that make the handling predictable and give you the greatest confidence behind the wheel. Provided that the settings you choose lie somewhere between the extremes of soft/hard then you know that the suspension is right for your car and purpose.

Personally, I think of The Ring as a relatively smooth fast road rather than as a "track", and in parts it's not dissimilar to the road network around my home, except my roads are much bumpier and have dreadful surfaces (hence my dislike of the OEM suspension); consequently, I'll probably prefer just slightly stiffer settings than you at The Ring and am prepared to anticipate the bumpy bits as being way better than what I'm normally used to driving on. In the past, I've driven on the skid-pan facilities at The Ring, and know that in the wet, soft suspension is much safer than hard, so I'm always prepared to adjust my suspension according to the conditions because it does make a huge difference in handling.
 
Looks great!! I was on the track probably at the exact same time as you!! when looking through the photos that people take from the outside I saw your car a few times and wondered if it was forum member! looks great mate.

What a great day for racing on Sunday afternoon though!! :thumbsup:
 
Good vid :thumbsup:

You know the track better and used more of your cars performance, than he did it seemed. He seemed more comfortable in the higher speed stuff, that RS must feel very planted at high speed.
