I went to Nissan to get a price on some ball joints, as expected, they will only sell the entire lower control arm with Ball joint already fitted for the bargain price of $545 each! The tie rod ends were nearly as bad - $220 each - bloody ridiculous.
I have been to Repco, and they can only supply the entire Ball joint, but not the rubber boot on it's own - didn't bother getting a price.
I called Wilkinson Suspension in Bayswater, and they have quoted me $115 to supply & fit new ball joints to the existing arms, as long as I remove the arms and take them in - no problem - that's what I will be doing!
I got most of it bolted up as a Dummy Fit, and it's looking good. Ran into a small problem, which can be easily rectified. The top bolt for the calipers is directly in-line with the lower bolt of the strut, and there's not enough clearance for both. Luckily, there seems to be plenty of meat in the adapter at that point, so we should be able to recess the bolt enough to clear the strut bolt.

Yet another change of plans this week. After it being suggested that the Pedal Ratio on the car may be no good to run un-boosted (Thanks Dalspec), I took some measurements and sure enough the pedal ratio is only around 4.1:1
This means I will have to shelve the balance bar set-up and run a full pedal box.
Yesterday I removed a fair portion of the braking system. ABS Unit is out, master cylinder is out and the brake booster is out (what a bastard that was). I have also removed the Cusco breather can, as we have to run a much larger one to go racing, from memory it needs to be 1 litre capacity, but I need to check on that. I can now start planning the balance bar set-up and deciding on which master cylinders to run. I also need to design the bracket which will hold the balance bar.
I have dropped off the rotors we plan to use to have the centre holes machined out to fit the S15 hubs, and once they are done, we can also dummy up and make the calliper adaptor brackets.
While the calliper adaptor brackets are being made, I will also get the machinist to modify the strut tops so that I can maximise the amount camber, as we can't run adjustable arms under IPRA rules. I'm hoping to get 4 degrees of neg at the front, which should be more than enough.
Next time out it will have the new brakes, wheels & tyres. I'll also have all the springs rated to see what I have and adjust accordingly. Also planning to modify the existing strut tops for a little more camber, and then check all the roll centres. Finally, I'll tale the car to Andrew at Hyperdrive for a quick tune to make sure the engine is safe......plenty to do!
Just read through your thread, great read and great to see someone getting into track days.
I started doing track days 20yrs ago, and have never looked back. After building an SR powered Datsun Sunny race car which I sold in 2010, I have just recently picked up an S15 to turn into a track car/ race car.
I'll be following your progress, and hopefully we can exchange notes.
I have lurked around the edges of the forum for a number of years. Finally, I have picked up my first S15!
The car I have bought will be built into a dedicated race car. This will be done on a budget (of sorts), however I will spend the money where it is required. The current specs as purchased are:
Nissian Silvia 200SX S15 Spec S 2001
Apexi AVCR Boost Controller
HKS boost gage
HKS air filters
Cusco strut bar
D2 Full racing suspension
Cusco oil catch tank
Apexi Power FC ECU
Apexi Turbo Timer
Competition quality sound system (First thing to go)
ORC Twin plate carbon clutch and lightened fly wheel
Aftermarket exhaust manifold
HKS Dump pipe
Full HKS exhaust
18 inch Gmax deep dish rims
Running 300 bhp

Over the coming months I will be pulling the car apart and making a number of modifications to get the car ready to run in the "Improved Production" category at Barbagallo Raceway.
To make my life easier, I have set up a Facebook page to chronicle the development. If you are interested, feel free to like the page and check in every once in a while.
The car is still registered, so may even make a cruise or two until it gets taken off the road for good. I'm sure I will have lots of questions and using the Search function regularly. If anyone has any questions, please feel free to ask.
Also, if anyone is interested in getting involved with helping build and run the car at the track, please let me know.
