My brother got a flat on his Integra yesterday, and I saw that he and dad left his emergency spare lying on the grass outside the house... I went and asked why (cos I was worried it would get stolen) and they said because his other (aftermarket) wheels are much larger than the spare so the car wouldn't be straight, and therfore it was useless. Now: I'm pretty sure they are just +1, so the spare SHOULD fit and at least drive the short distances it was intended for, right? I've got 18's on my R33 GTST (so I guess that's +2), and my spare looks TINY compared to my rims (even smaller in comparison than my bro's looked), but the spare should still be useful right? It's the outside/rolling diameter which is important, and I'm pretty sure mine are the same as stock...

Would you be overly offended if i said your brother and your dad are retarded?

If his aftermarket wheels and tyres maintain the same rolling diameter as stock (as they should if they are a regular +1) then it's no different to having a space saver on one corner and stockers on the rest.

Regardless. All the thing is there for is to get you to a tyre shop. If the car crabs for all of 15 minutes while you head for the local bob jane does it really matter? It's certainly better than being stranded on the side of the road, or better yet, leaving the car there with one corner held up with a scissor jack while you wander to the tyre store (after waiting an hour or so for a mate to pick you up).

i heard from the tyre dude that if you have aftermarket rims on your rwd, it's advised that if you get a flat rear tyre to move one of the front rims to replace the rear flat and run the space saver on the front.

seemed logical at that stage, considering the loads on the diff and driveshaft, etc. i didn't really give it too much thought. same apply in reverse on fwd?

how fast are you planning on driving on the spare? coz if the answer is fast, then you're an idiot. if the answer is quite slowly limp it to the closest point of repair, then i dont think any of this matters too much. even if the rolling diameter isnt the same.

No! Find the tyre dude and slap him.

Put the good tyre on the front (So you can brake & steer) and the space saver on the rear (less weight, less braking).

This is true for FWD, RWD & AWD cars.

Lastly next time you go to the servo check the pressure in the spare. They need a heap of pressure to run as they are so small. Using a foot pump will take you three days to inflate them. No point carrying a spare if it doesn't have any air in it.

Beat me to it^^^^^^^^^^^^

I've heard its safer to put the spacesaver on the rear.

1st Reason: Braking - When a car brakes hard most of the stopping is done with the front wheels.

2nd Reason: Cornering - More force is put on the front wheels during cornering.

3rd Reason: Weight - Most cars are heavier in the front than the rear.

I thought as much too. Thanks. I explained it to Dad who I think was the one who went 'that won't be any good!'

BTW, that teg goes HARD for the amount of effort/petrol he (doesn't) have to put into it. Meanwhile mine sits out back with a busted turbo while I save up :(

    • 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.
    • Well they got my money but they are not getting my gearbox ! 
    • It's needed for rolling idle up, and I think it is a decider on VCT also.
    • I mean, not really. Link ECU's can absolutely still have errors from the ECU thinking it's getting a sensor it's not expecting. I would imagine the speed at the ECU level in Nistune does absolutely nothing anyway? I assume the ECU does not do any fancy TC stuff with regards to front+rear wheel speed or anything of that like anyway. Someone who uses Nistune may be more fluent in it.
