The IS300 is a very elegant sports sedan but it's not until it gets the right suspension that it transforms into a beast. Many people agree that the IS300 is the sportiest and most aggressive looking model from Lexus. With its front mounted engine, rear wheel drive, and optional manual transmission the IS300 becomes a great candidate for tuners to build fast street/track cars out of.  Even though the IS300 is on the pricey side of cars, the features and quality are worth the price. There are many ways to upgrade and speed up the IS300, but one of the things that will make it not only look good but perform a lot better is the suspension. Coil over shocks are used in mostly every race car and even by the majority of street cars. The improved handling, ride height, and adjust-ability of the shocks make them better than any other kind of strut and spring setup. There are many different companies that offer coil over shocks and they have different applications for different types of cars and driving styles. We take a look at which option is the best for your IS300 and your type of driving.

The first set to look at are the Cusco Coilovers. They are made out of thick and rigid aluminum which keeps the weight down and the durability last a long time. Users say that fitment is pretty much perfect, even the abs and brake lines are very percise and fit right on the dot. They come pre-assembled and adjusted to a factory setting and are easy to adjust to personal liking. Drivers who have had these coilovers say that after 35,000 miles of rough cornering they still love them and have no problems. Another great plus is that these coilovers have pillow balls, which don't make noise. In an IS300 luxury is expected and loud creaking or any kind of noise from the pillow balls would make the car feel cheap, luckily with the Cusco coilover system that will not be a problem. The only slight downside, a number of drivers say that these a bit more bouncy than expected during regular driving and even small imperfections in the road can be felt by the occupants. Even though the ride is a little bumpy, users did say they can corner around 20 mph faster on most corners. If your looking for something tough that will last a long time Cusco Coilovers are something definitely worth taking a look at... product link

If your looking for an affordable set of coilovers Megan Racing Coilovers are a cheap way to upgrade. Some people felt that these shocks were a replica of the Ksport coilovers but after testing them out there are many differences. One of the improvements over the K Sport coilovers is that the clunk noise is gone that the Ksports have. Another nice thing is that they don't have as much bouncing around, which makes the ride a lot more comfortable while keeping the damper settings tight. Both these coilovers are an upgrade from stock although the Megan coilovers seem to be a upgrade to the K Sport. One of the bad things about the Megan coilovers is that users complained that the fitment is not very exact. Some people had to dremel out holes and make them into an oval in order to get bolts through. For the low cost of these coilovers I still think it is worth it if your on a budget. The k sport are not as good as the Megans but each driver has their own preference and may like the k sport over the Megans in their own way. Both of these coilovers are mostly best for street and looks, while the track times will be improved over stock the gain will mostly be seen on the street.
