Yes, I have experience, gained from driving my friends’ lowered cars
You will in all likelihood no longer like the ride quality
And you’ll probably start scraping the bottom of the front bumper every time you pull into a driveway, parking garage, etc.
Yes. On my old Mustang (2003) I had Eibach Sportlines. They ended up dropping the car too much (2 inches). On my current Mustang (2016) I went with the Ford Racing X springs. which is supposed to give a 1 inch drop all around. At the same time I went with bigger sway bars and new tires/wheels. The car came from the factory with staggered wheels, and consequently a set of tires lasted about 12k-16k miles. I decided to go with a square set of wheels (20x10) that I could rotate with a bit more offset to get the wheels flusher with the fenders. stock rear tires were a quarter inch taller than the fronts, giving the car a slight rake. I wanted to maintain that so I had 1/8 inch spacers put on the rear springs. Combined with the lower profile tires, the effective drop was 1.2 inches in the front and about 1 inch in the rear.
There are mobile wheel repair services that might possibly repair that for less. Wheel finish repair has become very common, many Lexus dealers perform this service daily as part of the available tire and wheel insurance plans.
The compromised ride quality would be considered to be the most noticeable problem by many people. I would not tolerate the ride of a lowered Lexus IS, they are low enough from the factory. Also, the seating position is so low that getting in and out of the vehicle is more exercise than I want.
Setting up the vehicle lift for a lowered car is a chore for the technician, you wouldn’t make any friends at the service center. You will be the guy impeding traffic by slowing for dips in the road and crawling up parking lot entrances.
I have worked on many lowered Lexus IS cars, common damaged areas include the front bumper covers, missing under engine covers, damaged plastic covers under the seating area, damaged or missing fuel tank shields, rear suspension covers, and charcoal canister covers.
The exhaust system, oil pan and transmission are high enough to avoid damage, if you run over something big enough to damage those, the radiator core support and crossmember would be damaged first.
Thank you. Once again, I’ll erase lowering the car from my dream list.
The car drives so good as it is now.
Btw: today a 2003 Camry beat me. I don’t know how he did it. I just couldn’t catch him despite flooring it. Strange to me.
Which engine do you have? An aggressively driven V6 Camry could give it a good run.
Elaboration on 2003 Camry beating me.
Today, a 2003 Camry was tailgating a car in front of him. I was behind him. I know the road very well, and so does the 2003 Camry driver. I decided that I would keep up with him when the road changed from a single lane to a double lane for passing. The stretch was about a mile. Once the road became double lane, the Camry floored it, and so did I. But his car kept leaving me and was speechless.
V6 engine. And my car was kicking. But that old camry was wild.
Which V6? The IS250 or the IS350?
Either way, once the Camry got a jump you’d have a tough time catching up.
I believe the v6 for the 300 and 350 are the same but the 300 is detuned to 260hp.
Possible the Camry had a tune in it… I don’t guess you could hear the exhaust sound to tell if it was different?.. (respectfully asking)…
I have had a few Camrys and Corollas try to mess with me and a few were faster then they should have been, so something had been done to them…
Most likely tuned, or like texases said: it got a jump before me. Funny that you just wrote about it because I’m here thinking about the Camry, too lol.
And no, I didn’t hear any sound from the Camry.
Jump or not, if it kept pulling away then it was the faster car, your F Sport (IIRC) should be the faster one and you should have been slowly closing the gap, rather you could catch up or not, not it pulling further away…
I can get a mean jump on a Scat Pack Wide Body, but that doesn’t mean that around 50 mph it doesn’t drive around me and drive right out of my life…
In my neck of the woods, the only parking blocks are directly in front of convenience stores, or in small strip malls. These devices are apparently placed there to keep people from driving into the adjacent storefronts.
Unfortunately, they don’t always work.
Bollards work. The concrete fillled steel pipes cemented in front of the stores. A local Target uses large round cement balls which look pretty attractive.
If that bothers you so much, then you really have issues.
And this is from someone who is worried about their driving record points.
I fixed it for you. 
That looks like there WAS a bollard between those 2 wide spaced ones… What are the odds two people would hit the same spot in successive crashes? This driver should buy a lottery ticket!
I am worried about points, of course. The one mile stretch when the road became double lane is impossible for police to patrol. This is why I said me and the Camry driver know the road very well.
If I could afford a real sport car I’d go with one over a Lexus IS. Been a lover of sport cars since I was a kid. And since I can only afford the poor man’s wanna - be sport cars, I have to live with the huge fender gap
