all, 

Full engine rebuild forge and happy with car however there is no grip or minimal

 

I am thinking of fitting michellen pilot sport 4 s to rear. has anyone fitted this and is it any good?

It was the recommended tyre for m5 . It is currently falken and it is shit as there is no grip and spinning in first , second and third

 

running 500 bhp.

 

I checked tyre pressure today and it was 7 psi on passenger side and I had driven it 200 miles back . car was as wobbly as hell and I am lucky to have survived this ...

 

Would low tyre pressure at rear make car wobbly?

yes it absolutely would. And no, particular brands of tyres aren't shit, they all have better and worse/cheaper tyres in their range, and as tyres get older they harden and lose grip too

So, I'd look at the performance end of any manufacturer's range, if you are looking for value someone like falken (eg FK510) is a good place because they have performance tyres but don't charge brand premium like michelin, dunlop, bridgestone etc

Personally I've got dunlop dz102 on the stagea which are fine and dunlop sport maxx rt on leaf for road and occasional hillcimb use which are good, but there are a million opinions about performance tyres.

The Michelins  would be good street tyres but I believe they are quite pricey. Have a read through the tyre thread to see what other people have used.

As per Murray's suggestion I had a spare set of wheels with slicks for the track. if you can afford it you could buy new ones. I used to buy used tyres from the V8 racing teams. They were fine for my purposes.

Yokohama AD08R is a good street tyre. I will be going back to these after...

Hankook RS4 which started out as a good tyre but is just as noisy now that they are >50% worn as....

Kumho V720, which is a good tyre but it is excruciatingly noisy after the first 2 weeks.

All of these are about as sticky as road tyres get without being kidney money. None of them are really suited for keeping 500HP in check in 1st of 2nd. If you're not going to go a 2nd set of rims with dedicated semis, then this is the most sensible territory to be looking in.

As the other guys have said, there are other candidates in other manufacturer's ranges.

Many thanks 

 

are any of these as good as michelen or pilot sport 4s

 

looking at pricing they were £80 each compared to £190 for michellen

 

here people swear by michllen for m5 which is similar power but really struggling to justify £400 for two tyres

Yokohama v105 on my GT-R. 482bhp at the wheels and these tyres hold up very well. Happy to support a local supplier that also does the wheel alignment.

For the Toorak tractor, I take it wherever is convenient and well priced.

Yeah totally but local tyre shop bridgestone reoo3 for example $1400-1600 tyresales $$950-1050. 

Check the dates of manufacture on the sidewall of the tyres from them. Old stock tyres is why they are cheap no thanks.

Just read an Aussie test of ten tyres and Dunlop Sport Max came out on top in most categories. I was looking because my new (to me) car came with a set of brand new HiFly 805 (and they came between 8th and last in everything?).

That's what I have on my car (dunlop). Fantastic tyre and good value for money.

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
