    Better Power Steering performace at Cold Start (weather)

    That is great. i think to reduce the amount of Engine oil required for the optimum viscosity i should be usig highest viscosity available right ? like 10w-60.

    Hi. Thanks all for answers. No Leak at this point Manual specifies Pentosin CHF 11 This is very attractive suggestion :) Wouldn't Engine oil be bad for Seals and cause leak ? Should i use mineral or synthetic oil ?

    Resonator Vs Muffler instead of Test Pipes?

    Well. Test 1: Transmission in Neutral at 3500-4000 RPM there is high noise outside. But inside it is pretty fine. Doors and hatches are Matted+ closed cell foam (IMHO outside noise is not more than other cars. I had other cars that made similar amount of noise at 3.5-4k RPM. Even all exhaust...

    Resonator Vs Muffler instead of Test Pipes?

    Hi. Hangers are rubber. At idle in Neutral, there is almost no noise. At cold start, if i put Transmission into D and press brake pedal, there is pedal shaking noise 35Hz. Too Bassy. Noise is more problem during engine load, not directly RPM related. I rarely exceed 3500 RPM, So During...

    Resonator Vs Muffler instead of Test Pipes?

    Hi. Friends. Unfortunately i am back after much effort :( 1. Replaced muffler with used one. No success (Didnt risk new one because not sure if it will help or not.) 2. I thought the noise would be emitted from Muffler itself. Bought 2mm steel sheet to add aditional layer over stock muffler...

    Resonator Vs Muffler instead of Test Pipes?

    Thanks for reply. Do very small holes make loud noise ? For example one or two toothpick sized holes due to poor welding at difficult to reach areas?

    Hi Friends. For the outer surfaces of car where it is exposed to dirt, stones and water splashes regularly, rust prevention may require a little more extensive work, But most of in my case, there are small areas inside (such as door hinge, footwell, at some cable connectors) that i see sign of...

    Center of Gravity and Roll Stability

    Hi Friends. My question what type of correlation between center of gravity and roll stability? is it linear or non linear ? i made some search and found this study: https://www.hamilton.ie/selim/SolmazAkarShorten_Yale08.pdf But it is too technical to understand for me. Regards.

Continental Front, Michelin Rear Not only did Rim/Tyre ratio visually make it look better, but swaying reduced IMHO, and ride comfort improved. With old tyres, car in stationary...

    Does upsizing tire affect acceleration in all gears?

    Hi Friends. Please correct if i am wrong, If we upsize tire diameter by 10%, we would feel the sluggish acceleration all the time? Because depending on the gear and our cruising speed, most of the time, engines are running at lower than optimal RPM range where it can deliver decent amount of...

    Hi. W163, ML320. Installed 20mm Spacers on front, and it had improved look significantly. It run without an issue for a year, now planning to install rear ones. Just for look.
