260DET

Bloody book of faces ☹️

Another OBD2 option I'm told is to get a wireless connector that plugs into the OBD2 port and a car orientated Android screen device with GPS for relatively peanuts eg 9" screen device on ebay for $133. No data logging of course but all that's presently needed is a in car display of a fair size, the above solution sounds almost too good to be true. Anything to look out for, anything in particular that the Android device should have? Thanks, if there is helpful interest I'll do pics and details in due course.

Can't argue with Fatz' Audi, be a lot more satisfying and comfortable to drive on tarmac than some last century ladder frame.

Not sure if this is a + or a - but John Bowe will be there dispensing free advice LOL. Wish I was going this year ☹️

Challenge Bathurst weekend 17,18 Nov 2018, cost $1690, 2:36 minimum lap speed, log booked and road registered cars eligible, share garage. More info at the Challenge Bathurst website, the Z Car Club Q being an original contributor is allocated a number of places with one entry being cancelled hence this offer. The club's contact is David d1770@tpg.com.au for EOI's, this spot is only available through him. A great well organised event you will get plenty of laps with a mostly well behaved group of Datsuns and quite a few other makes too, it's Bathurst and will never be cheaper.

Thanks Blue, that helps.

The final decision for my project is to go with a management system that supports OBD. So my question is, what OBD compatible dashes are worth looking at?

The hardest thing I've found is accepting that in spending money on a race car means basically saying goodbye to it. That's OK when it's just a few dolla, it's the big chunks that hurt but if those big chunks work then over time then I'm pleased with making the right choice. It's usually when I've tried to compromise that mistakes are made. My philosophy is if the money is spare then spend it, if motorsport really is your thing then do it while you can. One example for you, go five stud and get a really good aftermarket brake kit, two piece floating rotors, the lot. You S chassis people are spoilt for choice.

Basically you can't afford what is needed, this is probably why some commentators get frustrated. There are heaps of things that you could do like big wide wheels, MCA suspension but if it all comes down to the $ then it gets to be a personal thing. You just can't expect to compete with the $ cars, what you can do is keep tweaking what you have and enjoy the challenge of different circuits. Race against yourself, you can always do better.

Of course optimising what you already have will cost you more and thoroughly investigating weight and cost is part of that process. What I find is that most don't do this thoroughly but instead take the easy well known option which is not always the best. Let's take brakes. Have you searched every option available? There are online sources such as Ceika who offer a wide range of kits, their stuff looks to be good quality but I have not used mine yet. Their downside is that the adapters are made of steel and can be heavy depending on how big they are. At least you choice is clear, optimising what you have or go with a heavier more powerful car that may or may not be faster, depending on the circuit. On the subject of circuits, go to as many different ones as possible. How about Bathurst in November?

On people airing their opinions, that's OK if they are on topic but can be quite annoying when posters air opinions that in reality are what they would like or prefer and have nothing to do with the OP. It also helps some people when trying to make a decision to write down their thoughts, relevant responses help in that process. Only comment I have is not to forget to check things like can your present box type can be upgraded, same with the brakes eg better cooling, better pads, better calipers, etc. You have a low weight advantage that is quickly going to be lost if heavier bits like a 32 box are fitted. There is something to be said for optimising what you already have, it's the package that's important, maximum performance with minimum weight.

Bugger being fair, with a race car you are putting your life and others on the line.

Dan has all the skills to be a worthy world champ, I fear that he will never get the car to match those skills. A pox on Renault.

Aim have an local office, they will likely get my business.

It depends on a few things including how much spare time you have but it sounds like you would be better off buying a suitable track car at the right price and going through it in between races. One thing I have learnt with a modified car is not to trust other peoples work unless you are familiar with the quality of their work, the things some people do with a race car is unbelievable.
