Lexus IS: Regretful Modifications

It feels horrible to spend money on a modification and regret it later. Let us help steer you in the right direction before it's too late!

This article applies to the Lexus IS (2005-2013).

We've all done things that we live to regret in life. For gear heads, this includes modifications we wish we hadn't even attempted. Whether those mods made your ride look or perform worse, or they simply broke some expensive stuff, there is no worse feeling than a mod gone wrong. The mistakes of others are a great learning tool, and by doing a little research we can save ourselves from suffering the same agony they did.

Buying the Wrong Model

One of the worst mistakes you can make that isn't really a modification is buying the wrong car in the first place. We may have a tough time justifying spending the extra cash for a bigger engine or an F Sport model, but it may not be long before you wished you had just made the sacrifice. The worst part is, you are probably locked into at least a five year payment cycle, on a car that is upside down once you drive off the lot.

Aftermarket Alarm Systems

Not to say that there aren't quality aftermarket alarm systems out there, but you may want to think twice before installing one. Playing around with wiring on a high-tech vehicle can cause the sort of electrical nightmares that many forum guests have reportedly been haunted by. Those kinds of problems are ones that can be fixed, of course, but it may set you back thousands.

Tires That are Too Big or Rub

Usually bigger is indeed better, but you reach a point where tires are simply too big for your ride. What happens next is rub, which is not only annoying, but it can destroy that expensive set of rubber you just paid big bucks for. Make sure you do your research and buy tires that are nice and meaty, but not to the point where they rub.

Buying Springs but Not Struts and Shocks

A lot of guys buy springs to lower their cars, but don't upgrade their struts and shocks at that time. The reason is cost as struts and shocks are pretty expensive, especially compared to the cost of springs. But you are better off waiting a bit longer and saving those pennies because stock struts can't handle the added stress of lowered springs. You will only end up with a harsh ride and premature wear.

Buying Cheap Aftermarket Wheels

Not only can some cheap aftermarket wheels scratch or show wear quickly, they can also be dangerous. Several forum members have reported wheels that crack after a short period of time, which can be a scary proposition if you are traveling along at a decent clip or taking a fast corner. Quality wheels can be pretty expensive, but in this case you usually get exactly what you pay for.
