Trackcar Q & A thread 3 Years, 1 Month ago Karma: 326
Thought I would put this thread up. There are lots of people creating track cars at the moment and perhaps this would be a good place to ask any questions or put up some advice for others.

My 2 cents, light wheels and good brakes is the best start you can make.

My questions:

Who has bypassed the heating matrix, any photos.

Anybody considering removing the crash bars front and rear, I am thinking about it.

Re: Trackcar Q & A thread 3 Years, 1 Month ago  
I'm starting mine this Wednesday, trackday/future classics car. Only got the garage space y/day so progress should speed up now. I plan to remove as much weight as possible from the car but also include safety equipment (cage/seat/harness/fire system). I will remove the crash bars and any other weight. I talked to my brother y/day about having a heater for when the windows mist up and he said he's removed his from his racing car and uses a switched 12v travel hairdryer and some ducting to demist the windows!!!!!! Not sure if he's taking the piss. However I plan to remove it and the air con so guess we'll find out soon enough

Might get some of them from you Japohara, will you wire them up and all for me, pretty please.

Also for anybody going to remove the heater matrix, see the photos below, pipes work out perfectly. But they are a bugger to break the seal on, also be careful with the pipes as they bend very easily.

We removed the front and rear crash bars, only problem is the towing eye is on it for the front. Big weight saving in changing the glass to plastic, removing the door mechanisms and using a bit of wire to open the door. Spoiler weighs a good bit and doesnt seem to do a lot when its on, dash and interior plastics are heavy, all you need it there is the cluster. Standard seats are heavy, but the bases can be used to fix buckets onto so dont throw them away to soon, we have never had any issues with steaming windows, no fan, heater matrix or anything else in there. Removing that stuff leaves a good few holes in the footwell, its easy to direct the air that blows in there up to the windows, or to your feet if its warm. Good cold air is a good option, we extended the air filter piping so the air filter actually sticks out the side vent, no hot engine air getting into that.

Best option we ever put on the car are really good tyres on the 15" rims, go for tarmac rally tyres if you can get them, they out perform any spec of road tyre we could find by a long way. Yellowstuff pads are cheap and work and last well, good quality brake fluid is a must, we also de pulled the fuses for the ABS with no issues.

Mistakes we made? Fitted small mirrors from a motorbike, may as well put the wifes compact mirrors on there for all you can see out of them. Used tyres that were not rated for a car as heavy as the MR2, they just buckled round corners and left you going round on the rim edge. Lowered the car to much, it affected heavy braking by bottoming out the front shocks and making it bounce and lock up.

All in all, a very capable track car once its set up right and weight is taken out of them. We swapped parts we removed, made up and butchered parts from other models to get the niceyes that cost money, such as bucket seats, suspension and tyres. Ours costs us much less than some other cars take to run for the day and reliability is as good as we have found, cheap trackday car.

I got rid of my heater, fan and A/C and i had no fogging problems, there is plenty air getting in through the holes that are left there.

Duct tape? you dont want to be adding extra weight lol
leave them open, sitting in the car with a helmet you get just the right amount of breeze if you open the windows about an inch.

The holes allow you to get some air in round the dangly bits that heat up some in the pit lol.
