thats one hell of a first post! welcome to the forum
cc @NYG as Im sure he has some thoughts/advice

 

Great car!

Have you considered a lithium ion battery (save about 12kg from the front end) and a super light weight exhaust for the equivalent weight saving at the rear?

Also the carbon fibre antiroll bar really does sharpen up the front end. Well worth a look.

 

Thanks for the advice!

I suppose the capristo can be considered lightweight.
I will look at the battery, have you got any brands or references to share to make my search easier?

Same question for the anti roll bar, not only it could help, but it would be like a cherry on the cake in terms of looks!

 

Welcome and congratulations.

 

Some nice mods you've done there.
WRT to brake fluid, either Motul M600 or Castol SRF works well.

 

Welcome @Slappymangooze ! Always nice to see another R8 track guy - there's not many of us here. I haven't tracked out my R8 the way I did my previous BMW or Corvette so I can't recommend seats/cage (@Scott-AhlmanPerformance and @FoD are two guys that should be able to give you some advice on that).

As far as your brake fluid temps go, you'll want to run Castrol SRF. It's impossible to not overheat your brake fluid in a non-race car so the nice thing about SRF is that once you boil it, you can let it cool down and it will still be very serviceable while other fluids are essentially done. In order to control these temperatures for hard racing purposes, you'll need to route some brake ducts that feed air behind the rotor. I don't know what systems are available or if you'll just need to get some high temperature ducting and route it back there yourself.

Also, considering planning to move away from Cup 2s. The way your car is setup right now, you deserve more grip than those mediocre tires. I'm running Cup 2s on my stock suspension which probably can't handle anything more than that (it already struggles with track pads and hard braking). It's a great tire from the perspective that it's a factory tire with a ton of grip for road production cars but from the perspective of the track, it's very mediocre.

Hi there, I went and followed a bunch of your advices. Life got in the way and provided new priorities but I'm finally doing it. My car mechanic who worked on the GT3 Eco II is sourcing the race fluids. Regarding Tires, we will try a full combo race brakes, wheels and medium slicks. it should last longer than the cup 2's that only got 3 laps or so before becoming rather slippery.

 

@Slappymangooze Have you done Girodisc rotor conversion on front and rear? It will improve temperatures and they are really good for the track. I'm running front conversion and they work a lot better than the stock wavy rotors.

 

I have the wavy rotors on my c7 rs6 wagon, I hate them! Big let down from Audi to use them and not have proposed a recall. 3d time the 4 discs warp. I had ducts installed, no change. The 680 bhp 2 tons dog carrying machine living in the mountains doesn’t help, but still…

I run the stock ceramic. My issue is that I want to keep the car road legal, and Swiss people are not very keen on letting you change your rotors I’m afraid. I was told I should weigh the disks once in a while and see how much juice they still had. Anyone ever did that? Figures to share?

The giro disks seem like great value! I’ll keep it in mind if I get the balls to do something “illegal”

 

i think @Ape Factory supplies anti gravity batteries and provide more details

 

Congratulations and what a great first post. Absolutely love the green, If you had tan interior then I'd be jealous .

@NYG has already chimed in. Perhaps @Ricky.REP has some advice to add as I think he tracks a gen 2.

 

Tx mate. It’s the midnight green from inozotek.
Bought the car full black at the dealership but you are right. That would be a fine match.

 

Forget capristo.

If you are a racer go with the kline inconel exhaust. Weighs only 9kg!

 

Great looking car. And I’m another Inozetek wrap - Mamba!

As far as weight drop/track readiness, here goes. I went with an Antigravity battery. Extremely light. I also went RWD for some added fun and weight drop. I had the carbon front sway installed. I’m a Gen1, so it wasn’t straight forward. It didn’t drop any weight, but is supposed to be much stiffer. Running factory ceramics. Bilstein Clubsport coils, and a Capristo exhaust attached to LMS headers.

My biggest drop is from the Aventador Carbon Buckets. With my custom fabbed aluminum brackets, they’ll weighless than 29 pounds per. Fully covered in OE leather and alcantara with custom stitch. Shout out to Osman (R8-Stuff) for absolutely killing these!

I added a GMG half cage, but had my local artist fab up the cage so it resembles the OE GT cage. Still waiting test fit with everything, then it’s off to get powder coat and finally install.

Overall, I think I’ve dropped ~250 pounds off the fat girl.

 

Great looking car. And I’m another Inozetek wrap - Mamba!

These look amazing mate. How 'appropriate' are they for a 4-point harness do you think? Can't find a picture of anyone running a harness with the performante seats!

 

FoD you totally nailed it with the seat, dare I ask how much it would cost to do something similar?
Also, how are the LMS headers, made any videos?

 

PM’d you about seats. As far as the headers, I can definitely feel the increase in power. I had the Capristo put on at the same time as the LMS install to tone down the sound as I had straight pipes previously. Sound is perfect now. No videos yet.

 

hey guys,
After 5 years of using my car rather regularly (50’000km at the counter) and tracking it twice on spa Francorchamps, I decided to make it a little more special and capable at the expense of comfort.
We moved to Portugal, next to the estoril race track where I got to participate in two track days with the new config:

• Audi performance parts full kit
• KW adjustable suspensions
• Special brake pads on cc,
• Engine tune to 650 bhp
• Michelin cup 2’s
• Lightweight rims
• Wrap +ppf

As I learned the track, I kept pushing the car harder and harder.
No surprise that the brake fluid gets overwhelmed after 10 minutes of attack.
I wanted to know what was your latest experience with brake fluids, brake fluid radiator upgrades, weight saving?

i am considering the new recaro podiums that could the the most significant weight saver and on track comfort (I really wiggle around atm) and would like to add a half road cage to make things safer + have good seatbelt setup.

any up to date advices and references would be welcome.
Glad to meet fellow r8 owners in the Lisbon area!
Drive safe!

So, a few track days and a 1 & 1/2 year old son later, I finally pulled the trigger on some new improvements, courtesy of the new shop "Cars & Vibes" close to Estoril Racetrack, a supplier of racing car goods. I didn't notice how hardcore were the track focused guys here: From prototype builders for LMP1 to welders of FIA certified roll cages, I think I might be close to heaven. Very reasonable cost per hour has been announced, encouraging you to explore different paths.

A massive plus is to have been paired with a mechanic that worked on Audi GT3's

So here is what we are doing to my baby to keep it track relevant before the Donkervoort F22 arrives and scares the s*it out of me:

• Tow hooks
• Full service, oil, filters, fluids...
• goodridge braided lines for brakes
• Pagid rsc2 & rsc1 pads
• Michelin cup 2R Connect
• light battery and quick connect battery charger
• Audi sport Front anti roll bar CF
• Custom bolt on Roll cage (similar to huracan STO) powder coated
• Omp one 2 Versa Harness (and new helmet with Hans)
• Pair of Recaro Podium CF
• Telemetry: Aim Solo 2 DL with twin cams, OBD 2 connection
• First "agressive" suspension setup: lowering to get the best of the already upgraded suspension, (I'll just belly slide on speed bumps... ouch)
• Baseline track session with instructor for baseline establishment and develop and improvement plan.

That is all keeping the car homologated for the Swiss authorities.
But to really get the most of the car, the driving authorities in Portugal are rather permissive with brake kits, so here it is, a track special upgrade that I'll replace for regular inspection:
- GT3 EVO 2 Brakes, Pads, rims, and medium slicks.

That should do it , a blend of a GT4 in terms of aero and suspension and a GT2 in terms of power.
The whole work should be done by the end of summer. Patience is a virtue...
