10 Best Cars to Modify in 2025: Top Picks for Performance and Style

So many Mk4 Toyota Supras have been modified, it is very uncommon to find one that is stock. The sleek appearance of the Supra can be enhanced or altered to your exact specifications, whether you choose dramatic changes or more subdued adjustments.

They can be easily modified to four-figure power outputs, turbocharged Supras are the most sought-after Mk4s. The Supra could outperform some of the supercars of its era even in stock form, and there are countless ways to increase performance.

The Fast & Furious movie franchise included the car, which has been customised with a bottle of  "NOS" nitrous oxide and a bright orange paint job, among other things. This contributed to the car's appeal. Other cars to alter may be the Mitsubishi Lancer Evolution, Nissan Silvia, and Nissan Skyline. Japanese cars are frequently seen as an ideal platform for modification because they tend to be reasonably economical, reliable, and easy to tune.

This car is also one of the coolest looking cars, and on top of that, you can also try decorating it any way you like with custom stickers, like your name, favorite elements, etc. Use these little things to create your unique style. It should be noted that when choosing stickers, pay attention to choosing stickers that are easy to apply and remove and do not leave glue.

Although a car at the lower end of the market would require some maintenance and rust treatment, anyone looking to modify their MX-5 can find plenty of parts. These include V8 engines, body kits, superchargers, and improved suspension and braking systems. Roll cages and other safety features, along with weight-saving techniques, are fitted to May MX-5s to prepare them for track use.

Though it lacks power and is relatively inexpensive, the MX-5 is a popular starting point due to its rear-wheel drive, good weight balance, and first handling performance.

American muscle cars are just as easy to tune as Japanese vehicles, if not easier. The older models are more straightforward devices, with a large V8 engine serving as a strong foundation for increasing power output. The Ford Mustang is arguably the most iconic car in America, and modification businesses have been established expressly to work on these cars. Due to their extreme customizability, Roush, Steeda, and Clive Sutton Mustangs are nearly entirely new vehicles.

Factory Mustangs and Dodge Challengers can now be ordered with over 700 horsepower thanks to the American horsepower war, but enhancements are still available to make the Mustang faster on a drag strip.

Nearly identical twins, the Toyota GT86 and Subaru BRZ were designed as cost-effective sports cars that prioritised the driver over pure speed. The GT86/BRZ twins have always felt like they could handle a little bit more power.

An audience can be amazed by the customised GT86 and BRZ models that tuners like Litchfield can create. With upgrades available for the engine, suspension, brakes, and cosmetics, the two have earned a massive fan base. Toyota even debuted a limited number of GT86 models with liveries modelled after vintage Toyota race cars, which were pre-lowered and pre-wrapped.

Due to the Mini's iconic status, numerous businesses have been established expressly to provide parts and customisation options. No possibility has been overlooked. Mini have been stretched, lowered, cut, and modified. Engine swaps are also a possibility. While there are easily available Honda VTEC engine kits that are supposed to fit well into the small engine bay, more extreme modifications have included the addition of V8 engines. Given how much effort enthusiasts put into personalizing their Minis, car trackers have also become a useful addition, helping owners keep an eye on their prized builds, whether for security or performance tracking.

Because of the Lancer Evolution's WRC accomplishments, the Mitsubishi brand survived the 1990s. Before being discontinued in 2015, the Evo was a rally car, circuit racer, and street racer. It still has a lot of aftermarket support, which opens up a lot of customisation options and keeps the WRX as a constant rival.

The previous version features an attractive chassis and is simple to modify. The Evo community is among the liveliest, and you may seek assistance without difficulty if you run into any trouble with your evo.

Not many cars have a factory-approved power boost, but you can send your Ford Fiesta ST to Mountune for a tuning kit, and it won't even void your warranty. For a relatively small amount of money, the ST's driving experience may be totally transformed with the addition of 40 BHP and about 80 Nm of torque.

Since many accessories are under £100 and larger items may often be financed, the Ford Fiesta ST is actually one of the most affordable cars in the UK to modify. We observed that a remap package plus a Milltek exhaust system could be had for less than £15 per month for a period of three years.

The Honda Civic is one of the most customisable cars ever, having been in production for fifty years. The Civic, which started the trend of sport compact cars, can be fully modified to improve both its appearance and performance.

Due to their superb handling and reasonable price, pre-2000 Civics are the most often modified cars. There are indications that the new Civics will carry on the customising legacy, as evidenced by the newest model's stock turbocharged engine.

Honda made a special effort to build the S2000 between 1999 and 2009 in honour of the company's 50th anniversary. The fact that the S2000 was an excellent track car right out of the factory is the main reason it is worshipped among tuners.

Modified S2000s are frequently seen at car shows, the Honda S2000 boasts a devoted fan base, robust aftermarket support, and an expanding reputation. The car's prospects as a collectible appear promising because it was only produced for ten years and there is no indication that a successor model will be released anytime soon.

BMW M3 is a high-performance car ideal for track days and autocross competitions. It is a favourite among petrol heads who seek a car that is quick and enjoyable to drive because of its strong engine and rear-wheel drive.

A cold air intake, performance exhaust, and a fresh tune to boost horsepower are all possible upgrades for the BMW M3. For improved handling, coilovers and sway bars can also be added to the suspension.
