Hard Rubber On Tyres After Track

Hi all

I noticed that the tread or rubber feels harder after a recent track day

The tyres got pretty hot I think and felt greasy, and it was getting smudged all over the place such that I was getting rubber piles built up on the tyre (maybe i also picked up rubber off the track)

Is this a bad thing if the tyres feel like they are harder than before? grip seems to have dimished some what, maybe its just the tread wearing out as I didnt have that much to begin with before the track day. However they are certainly not bald yet.

The rears are worn on the outside edge (because I rotated the front tyres there)

Tyres get hot - then they go hard after they cool down. Happens to all of them.

You will get pick up from the track - have you also noticed all the random black smudge marks on your paintwork?

Is it a bad thing? Well if you want ultimate grip then yes it is.

Road tyres don't like track work. If you are having a proper go they don't actually last much longer than good R compounds....

Thanks djr

They are Falken FK451's, but yeah the rubber feels harder than pre track day. I guess maybe they werent built to handle the temps, dammit aye no on the street Im faced with less grip =~( thats not what I wanted!

So when there are huge worm like rubber bits stuck to yuor tyre, is that rubber picked up off the track, or my actual rubber from the tyre being smudged and rolled.

I noticed after the sessions I was able to pick iff rolled up chunks by hand, there were too many so I just left em.

It is mostly pick up. But check you tread blocks for the edges chunking.

Tread blocks seem okay, sweet its not my tyres chunking off like crazy haha

I hear that tread blocks tend to chunk off more with newish tyres?

The rubber on your tyres is picked up from the track. Why dont you just ring a tyre shop and ask away? See if your tyres are suited for track work?, ask if they will go soft again after a warm up lap? ect.

Unfortunately not many tyre shops know much or are very useful over the phone so I figured Id try here.

It probably wont see much more track days as the tread is getting low, need to conserve them for the street. Im more concerned about the heat cycling and whether its rendered the tyres dangerous on the road.

      You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.

      By cosline · Posted

      Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik

      Spotted on the street....

      By Rezz · Posted

      Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
