Very budget track build

Aleksandar:
Very nice build and it's interesting to see your progress regarding brakes and suspension... Would you remember what thread size the b14 are? And how do you find the ar1 vs ns2r?

Umm the B14 damper body thread is described as Bilsteins own thread, but lots of companies make parts that fit these threads anyway. It uses a 2.25 inch spring/spring seat. From memory I think the top mount thread is an M14?

NS2R is great, seriously people bad mouthe it for he wrong reasons, its decent in the wet on the road, good on track but it will get hot and loose grip eventually after maybe 10 mins but its linear so it gradually goes off unlike a slick tyre that may just go from on to off, plus its cheap and is still much quicker than your standard PS4 tyre.

AR-1 feel similar just much more grip and its like 80% of the grip instantly, the warm up lap is almost optional as its ready to go straight away as long as its dry.

So it passed its MOT.. somehow! And now roll cage prep and further lightening has started!



Trying to get this heater core out without having to drain the coolant is my current challenge, I just can't be asked getting under the car in the crappy weather right now :grin:

The heater core is 100% going though, I imagine it weighs a fair bit looking at the size of it and it has a TON of wiring in it too. I will need some rainex for the windscreen and rear window then. Part of me is thinking of keeping the heater matrix however, as it will act as a sort heat sink, I could possibly run a small duct to it or from it also for more cooling, my only concern is will it be impossible to stop the interior getting rediculously hot?

The main to do list looks like the following currently:
- remove as much wiring and unrequired items as possible
- relocate battery to interior (need a new gel battery)
- install new steering wheel
- ditch heater core for lighter solution

Its not going to be a quick turnaround I imagine though, as its all quite a mess right now! I'm still in two minds about adding a fibreglass vented bonnet and plastic windows for the front as a light bonnet and gutting the doors out and adding plastic windows equals about 30-40kg in weight saving! and all from the front end. We will see..

So I did try grinding the heater core into bits to try and get it out as a quick route but.... that does not work it turns out :grin: just made an enormous mess instead. I just spent some time doing it properly today and got it all removed. As you can see there is sh*t everywhere now :grin:




Feels like it weighs 5-7kg as a unit, but then there is the excess wiring, vents, the AC rad, condenser/compressor etc. By the end of it I think its a minimum of 20kg in weight if you ditch the entire AC and heater/blower system.

Nice big hole to fille now, not decided how I'm going to do it yet, will have to do a little research



Need to do a little cleaning and then I can start looking at removing unused wiring from the harness while there is lots of space + room, got some auto electrical tape to "try" and package it all neatly back together



Lots of other little bits to do, wiring new buttons, removing anything not needed, moving the battery to a much smaller gel battery inboard instead. make a nice fancy abs control panel for the centre console which is one job I'm actually looking forward to. cap off the coolant hoses, plug the firewall hole and some other little things I'm sure.

I need to consider what I am going to do about the doors, I would love to gut them as there is about 15kg each to get out of them but I need to find out if the cage is enough side impact protection or if I ought to retrain the crash bars in the doors.

Yup! Exactly why I was less than thrilled by the Racingline kit. Every aftermarket progressive spring I've tried has been sh1te. OEM ones are far better, but still not ideal. Linear all the way  :happy2:

Is that harness tape the OEM style soft felt type stuff? If so it's really good  :happy2:
