I have been hearing a lot of complaints about the Hyundai veloster turbo's suspension especially the rear suspension because it uses a torsion beam suspension instead of a independent rear suspension, does the 2015 kia forte5 sx and koup sx use a rear torsion beam suspension or a independent rear suspension ?

It's torsion beam.

that sucks,

We have the torsion beam rear suspension, which isn't really all the bad in my opinion with a little work done to it. Biggest thing is ridding the car of the under-steer and learning how to plant the car in a corner. Adjustable dampers/shocks and the right spring rate will control most of the issues, then adding the sway bar (which I have not done yet) will tighten it a little more. At stock height the rear has no camber and has toe in (factory set for safety reasons). Once you lower the car you get a little negative camber and will gain toe out (both of which help rid the under-steer). Not saying the IRS wouldn't have been better but everything that is stock on most production cars can always be improved on.

It's not bad that we have a torsion beam on our cars. Only thing that I think they need to do from the factory is better shocks and springs. If you add a torsion bar and Tork collars you will be amazed at how the car responds to it. I was super shocked when I got just the torsion bar installed by Eli at Evilla motorsports.

I notice I get a ton of rear chatter when mt rear wheels go over uneven pavement. Aka everywhere in colorado. Is it because we have this type of suspension? I don't know too much about suspension so barny style if you would. Lol

Knowing that my 2015 forte koup sx has a rear torsion suspencion makes me feel like the 2015 honda civic si is better value. the civic si gets, rear independent suspension, rear tale fin, sun roof, blind spot camera, and premium audio system standard, and only cost $1000 more then 2015 forte koup sx automatic base model,

Real hard to explain in Fred Flinstone terms, but if you look at the rear axle the part in the center that connects the 2 arms the wheels are bolted to is basically a large spring that is supposed to work as a sway bar. Any good amount of pressure from cornering hard turns that center part into a bow and when going over bumps it is losing traction a little and allowing the pressure on the bow to release. 2 or 3 little bumps in a corner will feel like the rear end has a "shudder". Good springs and shock help this by maintaining traction better and not allowing the bow to spring back as hard. The sway bar that eli has will not only help control body roll but is also bolted to the arm behind the tire from one side to the other and will also help control side to side movement of the arm.

I would post up an idea I have for a bracing system to eliminate this but I still have more work to do before it is ready.

All depends on what you want from your purchase, if you don't plan on doing mods to increase power then by all means the NA SI could be your car but if you are looking to have more possibilities in performance and tuning then you would want to stick with something with FI.
Not saying you can't turbo the SI but I hope you have deep pockets, plus everyone has a SI, ST, WRX, FR-S, GTI or GC and going through the forums they all seem to have their faults and owners complaining about something. At least with the SX you won't see one every other day, I have had mine for 1 yr 5 months and have seen 2 other Koup SX (4 if you count mine and 6th which is in another state). The choice is yours but I would rather have something nobody else has seen than something everyone has.

why should we have to spend money modifying our cars ? the 2015 Honda civic si gets a, rear independent suspension , rear tale fin , sun roof , blind spot camera , and premium audio system standard and only for $1000 more then the 2015 forte5 sx and koup sx automatic base models and its a Honda the most reliable car you can buy,

I do think the 2015 forte5 sx and koup sx looks better then the 2015 civic si sedan and coupe

lolololololol..... We modify by choice not because we have to, if you love Honda so much why did you buy a Kia?

Maybe the question to be asked is, Are you looking for something to tune and mod or something to just drive that has moderate handling and performance?

I wanted something with moderate handling and performance, i was not looking to do any mods, for some reason when my car has more then 1/2 tank of gas it feels fast enough but when i have less then a 1/2 tank of gas it feels slow, i dont know whats up with that, my car only has 2400 miles,

I live in south florida so i am thinkig about getting good quality summer tires to improve handling

That sounds weird to me. I believe it's a 12 gallon tank so six gallons less would be a loss of around 48 pounds. That should be around a 3 horsepower gain.

Where in Florida are you again?

Civics are nice. Kias are nice too.

Only thing I can say is you probably got excited about the car and felt you had to say yes without knowing what the koup f5 is about.

I knew more about my car than my salesman. I specifically looked for my koup based on the engine.

I know the smaller Kias use torsion rear suspension. It's not that bad honestly... Is it for a pure bred race car? no. But does it get the job done with being inexpensive and reliable? Yes.

Notice I didn't say cheap. I said inexpensive. That's what Kia is doing for the market. They are making things affordable.

Before my koup I was looking at 25k and up for a smaller turbo car. The koup fit my budget and the bill for what I want.

I only plan on maybe autocrossing my car so suspension is a big thought for me... Doesn't bother me one bit I have a torsion bar in the rear. It honestly moves and twists quite a bit. Just look at evilla motorsports videos.

If you want a fully adjustable and customizable suspension without "having" to modify your car. Your in the way wrong price bracket for a vehicle.

There are cars out there that can even shame Honda's in all aspects.

If you want longevity and length of life from your engine. Get a tdi vw.

You shouldn't be upset that your Kia isn't a race car. Believe it or not trucks are still using solid rear axles that were first developed with the model t and the like.

If you keep thinking this way about your car. Your going to hate it and hate it every time you get behind the wheel.

I'm thinking about getting Michelin pilot super sport summer tires, but my stock nexen tires are too new

 

[Forte5]

Once you change a few things on the car you will be more happy. I wasn't happy with the way the rear would sway or get upset on bumps but the Evilla torsion bar and trunk brace made it more planted. Changing tires from the stock crappy nexan tires will make a big difference in ride and handling. I want to change mine out soon to but I have other plans first lol

Every car is not perfect. Everyone will have something they don't like about a car after owning it. I didn't go for the Si because the F5 can outrun one in stock trim. Once we start modding and the Si starts modding we will still pull on them unless they go supercharged or turbo and have it turned just right. But the same goes for us. We build this car right and we will have a rocket of a car that will shut down even high end cars
