Hi all, I would like to try performance tyre on size 185/60/R15.
In dilemma now as I'm trying to maintain same aspect ratio while exploring performance tyre.
Reason is my current problematic car still under warranty, it's been through steering column, steering rack coupling replacement/fixed in this year. I don't want if (touchwood better not) steering component or suspension at fault again, SC got reason to blame it's caused by "thinner" profile tyre while I working at potholes road area. thanks.
so far i see all 185/60/R15 tyres are Eco-based, Yokohama ES32, Bridgestone Ecopia EP300, Michelin XM2. Performance tyre i mean like falken 914, kumho PS31.. don't see have this size..

As mentioned above, unfortunately no real good performance tires available at this size. The Falken 914 is NOT a performance tire, just a mediocre mid range one. Then the PS31 claims to be UHP but very questionable if true as stated in the below test by Tire Rack (some highlight quotes: "Dry performance falls short of "Ultra High," rubbery steering feel. ...not a tire for the driving enthusiast. Kumho's Ecsta PS31 fails to deliver on its Ultra High Performance Summer promise")

Is Bridgestone Potenza RE080 a good gripping tyre on this size?

Well the Potenza line up usually at least offers a decent performance for its respective class but not sure. Looks like it's the lowest model of the Potenza too with only an H speed rating so don't expect much out of it.

Potenza RE003. I am very satisfied with it

RE003 doesn't have the size that TS wants.

Hmm small car, normally 30-32psi is sufficient already but again you can always try to increase if will be more suitable. Note though that too high pressure will also reduce traction and therefore decrease stability. So besides increasing, you may also want to try reducing the pressure and see it that improves.

My original polo sedan Indian made absorber kaput within 1 year, so I change outside getting polo hatchback Germany made absorber. Polo sedan using oil based absorber no scrap bump, but polo hatchback gas absorber very stiff to compress but it's scraping bump easily, although both absorber same shaft length...

Weird, not making much sense. Dampers should not have such effect. If your car still using the same spring and the spring seats on your absorbers are also still the same height then the car height should be the same hence the ground clearance should also be the same. Absorbers also if stiffer then actually should have more resistance to compress hence the car should not go down as much.
