What mods can you do to a car to make it faster without having to tune it?
>>29050707Get lighter wheels and tires
>>29050707Lose weight you fat sack of shit.
A lightweight flywheel is usually a massive performance improvement for lower gears and at low RPMs. Weight reduction (wheels, 2 piece rotors, titanium exhaust, etc.) will improve the ride quality, handling, and acceleration slightly. A good alignment, good tires, brakes, and knowing how to drive will make you faster than 95% of people in anything other than a straight line.

Generally the only power adder short of a tune is to remove the catalytic converter, which is illegal in most of (if not all) of the first world. I've done it on 3 of my previous cars. Took an entire second off the 1/4 mile in my RSX, I used to live right by a drag strip so I tested often. Even if you live somewhere without inspections it'll sound like ass 9 times out of 10 and the power gain isn't *that* big for most cars.
>>29050742Depending on the car it might run worse nowadays, the ECU can only compensate for the extra exhaust flow before it hits a software cap on adding fuel.
>>29050707The first thing you do in Street Legal Racing: Redline is remove the hood, doors, interior, etc, anything that isn't critical to making the car move.
>>29050707In Gran Turismo changing the engine oil increased power (up to 30hp in Toyota GT1)
>>29050708You can get lighter tires?
>>29050802
>>29050814there can be a 25-30% weight difference between different tire models and the effect is more pronounced than wheel weight
>>29050814But the tire is the same in all three pictures?
>>29050707replace all of the glass with lexan
>>29050707Change the final drive ratio.
>>29050802Rubber is heavy af and high performance tires have tire weight in mind like instead of steel belts kevlar is used, as an example >>29050707Weight reduction, back in the day during the 90s and 00s tuner era is broke ass high school kids just dumped whatever we didn't need and gained instant performance. Sound deadening, air conditioning, power steering, back seats, spare tire and jack, dashboard, everything, all that was left was a tin can on wheels. You can shed like 200-300lbs and that was a HUGE performance boost back in the day
