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.

    • I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.
    • AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.
    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack. 
    • Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
