preparing for a multi car sprint help me

[jakesae101]

ok so next month im entering the gtz in a multi car sprint what things should i do im going to change the coolant and oil and filter. (any one have recomendations for the grade and type ) Change the brake fluid with some good quality stuff someone metioned motul stuff in another thread. Any opinions on some good pads was looking at the endless ones all round or atleast andother genuine toyota set. I need to change the accessory belts as they are almost at the end of ajustment . And i also need to mount and extingisher in the car was thinking directly infront of my seat. any other advice ???

Dont use self tapping screws to mount it, If you want to make it permanent (Not a bad idea to have an extinguisher in your car) first of all make sure you have an extinguisher with metal brackets that wont turn your extinguisher into a projectile in an accident, Drill 2 holes through the floorpan or transmission tunnel where you want to mount it and use about 8mm bolts with either 2 nuts on each or a nylock nut. Also use a couple of big panel washers between the floor/tunnel and the nut/s

Another way to mount one temporarly is to make a metal bracket up and drill holes to mount it between the 2 front passengers seat mount bolts and then attach to that

i was planning on the 2 8mm bolts with pannel washer and nylocks like i did in my escort

so any ideas with regards to pads that will be good for street with a track day or two a month

[Leon]

I've used and liked Mintex 1166 (0800 Racebrakes) in my AE92, and the g/f used them in her Pulsar road car. They're noisy, dirty, and DEATH to discs. However, they did well in my car on the track.

EBC is near universally considered to be absolute crap. However, I've never tried them (because they're considered to be absolute crap).

Other people say Hawks are good.

But, I can only report solidly on Mintex, because that was what I used.

Some people in the bigger cars have reported that the Mintex's have fallen apart on them.

Bendix Ultimate? dunno if you can get them for your car... how much were you willing to spend?
I try to swap my race pads (ferodo ds3000) out after going to the track cos it seems silly to waste the expensive pads on road/autox/small sprint driving.
Take spare rotors & pads to the track if possible.

Pads don't need to be great if the tyres are average... cos you can only slow down as fast as the tyres will let you.

[jakesae101]

there brand new tyres on the car some chineese brand but they grip really well ive taken some pretty fast corners in them and never had any issues with grip

[cat007]

+1 for 1166's - but yes from what I've read they can be harsh on disks! Although disks are cheap now anyway

Motul RBF600 fluid FTW - don't bother spending the extra for the 660, its not really worth it.

Also, on the fire extiguisher, I just bought one from the warehouse (1KG I think, was about $40) and it has a metal bracket. Is the passenger side of the tunnel the norm and best place to mount them?

[~SlideWays~]

Even good road tyres will be next to useless on the track after a couple of laps. Good Dunlop Direzza's for example will over heat and turn to crap.

But for a first time its hardly worth forking out for semi slicks anyway.

Go nuts though, awesome fun

[~SlideWays~]

Oh yeah, those DS3000 pc mentioned are bloody good but are about $320-330 for a set of fronts for the GTZ. Call Road and Track in Lower Hutt, they can order some in if you are keen.

If your going to be running normal street tyres, you will get away with some decent street pads.

When I first started this sort of thing, it was Eagle f1 tyres and lucas (green ones from repco'z) brake pads. When the tyres were pushed the brakes were getting near their limit.

Might be a little bit different with the extra huff from a gtz. But having said that if you have some rubbish rubber, you wont be hammering it into corners and thus things may be alright.

When I ran out of front pads last year at manfield, i threw in the best ferodo pads repco had at the time, and they were ok for the sprints.

remember your onlt going 3/4 laps at a time, things dont need to be super special.

Down the brake fluid line, Ive been using the grey bottle Castrol stuff for years now with no *issues*, its meant to be decent and is a good price.

[Distrb]

As previously said, you only really are going to require slightly tougher street pads as you are only running street rubber, so you'll reach the limits of the tyres before the brakes. I run 1166 all round in my ae92gtz and did a couple of rounds on manfield, and thus ran out of tyres before brakes (did a string of 1:27's tho) Bearing in mind they're about $600 for a full set of pads.

Something like ebc greens might be a goer for you, or perhaps even lower spec mintex (1155, or 1144?) or bendix heavy duty. Best to try a few things and see what suits. I know plenty of people that'll bag ebc pads, yet i ran some on the circuit for a while and NEVER had any brake problems.

other stuff to do:

- make sure your brake fluid is fresh.
- make sure you bed your new pads in before you get to the track
- make sure you have fresh oil and filter, and your oil level is just marginally above the full line (look after those engine bearings) and keep an eye on it during the day.
- make sure there are no loose items in your car, or things that might come loose when you're on the circuit.
- get yourself a twink or marker pen, and go round and do a full spanner check (i usually focus on engine bay, brakes and undercar incl all points of suspension) before you go to the event, marking each bolt or nut as you go through.

Basically you want to make sure that your car is in optimum condition before taking it on the track. Especially if you are driving there. coz you cant afford for it to let you down.

Oh rude word. I just been typing for the last ten minutes, and just deleted it all.

Prepare the driver, as well as the car.

Have an early night the night before, don't go near the booze or the whacky backy.

Take a lunch and a big big bottle of water with you. Keep hydrated to keep your brain lubricated. Otherwise you will end up paying $4 for a bottle of coke from Mobil.

Dehydration is the enemy.

Take a tyre pressure guage, some tape to attach numbers to your car, take a pen. Don't forget that the weather there is not the weather here. Sunblock, shades, hat good. Black jeans and t-shirt, maybe not so good.

Don't leave a camera lying around the pits, there are enough mongrels nearby that there is a risk it might walk.

Do your run. Come back to the pits SLOWLY. Park up, open the bonnet. Don't put the handbrake on, because you will end up melting your pads onto the discs. Let the adrenaline die down. Have some water. Check fluids, check for anything loose. Check tyre pressures. Front maybe run 34+ cold. Rear, maybe leave them 30 or so, otherwise it might get a bit oversteery. Check them after a run, and see what they are hot. You may want to put them up or down depending on how the car feels. Look under the car for any fluid leaks visible. Close the bonnet. Check that you've closed it properly, twice. Have another drink of water.

Arai.
But I work for the supplier so i'm gona say that

I've used a KBC motorbike helmet, pretty comfy, but vision sucks on bike helmets.

At moment using a Arai GP touring car helmet. NICE.

But Simpson are also good. Just depends on your budget

[Leon]

Go for a light helmet that is really comfortable to wear. Can't be much more use than that, as different heads find different helmets comfy.

[crispy'86]

As for the brakes thing (i know your talking about helmets now), i've always used lucas pads in the front of my car. (red pack with green lucas writing) from repco, they are good after bedding them in, after 4 stops they bite. And i mean really stop the car, i managed to lock up a wheel accidentally when i had my exhaust break, couldn't quite hear the tyre squeal, braked a bit too hard and flat spotted a tyre. Really good pads for stopping, i've done 5-6 sprints on them before getting down to the squeal tabs and having to change them.

Helmets, go to a decent motorbike retailer, or other place that specialises in race apparel. Find one that fits comfortably. Before this go here:

http://www.motorsport.org.nz/Pdf/LiveMM ... 20SchA.pdf
to check the requirements for safety labels for the helmets.

Street tyres in my experience, when i ran my bridgestone potenzas, i always inflated them to 34? psi cold. 40psi when hot, but experimenting is the key. Note down the changes you made and how they improved the feel of the car or not, then go out and have fun!!

bendix ultimate pads? anyone used these
