Has anyone run 225/50/16's on standard R33 GTST rims. I think from memory they are only 6.5" wide, so in theory 225 maybe a bit wide. Just after some first hand reports for street, track, or drift cause the standard 205 are way too skinny. Just trying to keep stock look, I have a set of 18" Zivell speed rims that I run from time to time, but rather run standos. Thinking about Kumho KU36 as I reckon they are good bang for buck.

Street slow=Fine

Skids=Fine

Any speed type driving=Fail

My car understeers like crazy if Im pushing with them on, and dont even think of boost, unless sideways smokey action and steering with your throttle or hand brake is what your after.

They are OK for day to day going to work and thats it.

My 2 cents

I agree with all of that besides understeer.. My current set are Re001 225's all round and it's quite taily. Maybe just the way I drive tho :cheers:

205's feel very direct but ultimate grip level isn't fantastic and they look ridiculous especially from behind. 225's look much better but there is a LOT of sidewall slop. I found running 40psi to be reasonable, anything less is horrible.

225's for day to day fine, put 40psi in them unless you drive like a grandma and if you actually want to have fun then strap your 18's on.

If I had to choose for day to day driving I would still run 225's because the 205's just look retarded on a sports car. And yes, standard fitment options are 205/55/R16 and 225/50/R16.

I'm running 225/50 on s15 rims- they look waaay better than 205s and I didnt notice any deficiency in handling.

That being said, even with the old cheap Kumho 205s, I had no problems with straight line traction unless I dropped the clutch on launch. They were even good for reasonable 1/4 mile times!

your contact patch for 205 vs 225 is actually the same area, so straight line traction should be the same. the difference is the 205's are long and thin and 225's are short and fat, relatively speaking. it's the wider cross-section that helps with cornering grip.

unfortunately 225s have too much sidewall flex so turn in feels very vague. also once you exceed the traction boundaries the tyre moves about and again feels very vague, there's not a "limit" as such that you can treat with finesse but an area where traction comes and goes. yuck.

    • Hi, i’m making a rb25det coil loom for Vag short coil. Can anybody tell me which Ecu signal wire belong to coil number 1 and 2,3,4,5,6? The connecting switch in above pic is 8 wire i think white is for +12v and black for earth.
    • Was there ever a model of the Stagea m35 that didnt have a badge on the grill? I thought I saw that somewhere, some aero edition or something? I cant find it again? davemoto
    • Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.
    • I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.
    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
