D2 Coilover

**BlueInfinity48** · 7-20-09, 17:56

Does anyone have any opinions on the D2 racing coilver for the first gen. Has anyone ever tried them. My buddy is co-owner of springrates.com and said he could get me the set for $915 shipped. That is the best price I ofund by far. So, I was just wondering if anyone heard anything about these on our cars.

Id say do a search on them but the search filter has a minimum of 3 characters. Long and short...D2 = k-sport = megan racing = function form = omni = hyami =.........

Actually, do a google search and youll find more than you need.

Gavin, you're not quite right in what you've said. D2 = G4.

K-sport not the same.....

**gavin** · 7-21-09, 6:09

Not familiar with G4 (or any other of the pink, green, blue, etc) variants.

There are three facilities(cant remember them off the top of my head) in taiwan where you can basically request a design, color and add your own labeling and voila, instant suspension company. D2 and K-sport are out of the same facility (or were as of 4years ago when I checked this out), D2 being the item with more features and k-sport with less.

Either way...commodity item.

EDIT: looked at the "G4" items...yep, looks like another clone

I contacted Justjap here in Aus about the G4 coilovers, they told me they can't stock G4's for the mx-6 GD anymore but then directed me to the K-sport as they said that K-sport is the same as G4/D2 and when comparing them, they do seem quite similar.

They are similar, if not the same design. However, not manufacted in the same factory. I have a set of G4's currently.....

They all come from the same backyard facility, made in a tent by a 5 year old Taiwanese kid!

hey were u still wondering about the d2 coilovers?

i run them in my GD mx6 on the street.

they are really good for the price and they look pretty lol.

only problems?

1. theres not enough adjusting thread on the front struts. this means that when its wound up to maximum height the crossmembers are 90mm off the tarmac. i had to use spacers in the top bolts to get through road worthy.

2. the springs are really really really stiff. and the spring rate is the same front and rear. so the back gets a bit bouncy if your weight distribution is too fronty lol. but i have ballast so its really good through corners.

other than that go for it.

For being the "same," quality seems to vary wildly between the brands.

Megan Racing =/= KSport, for example.

I use Megan Racing coilovers on my FSP Celica, and have nothing but great things to say about them.

Not really surprising that theres a lot of variance. If you think about it for a bit, you have different cars with a variety of different suspensions and weights. Its likely that one chassis will work somewhat well with the (very much NOT tuned to individual chassis) suspension systems out there.

Furthering on with the "not tuned" thought. That would also give you a lot of variance in and out of brands.

Does anyone really think for a second that a company can appear out of nowhere and have over 150+ applications instantly and have the rates/valving tested on all of those chassis? It just doesnt work that way in real world timeframes.

concealer404....FSP eh? Have you compared the Megans with another suspension setup(either on your own car or anothers)? It might be revealing. Not knocking your purchase, but you at least have to quantify your statement a bit.

PS: where do you live by the way?

I agree on the KSport sentiments. On GRM, someone found a dyno of their shocks, and it was pretty ugly.

Yeah... FSP. It's like bringing a plastic spoon to a grenade fight.

My motor is really weak, i have driveline lash coming from somewhere horribly. The motivation on this car is a gigantic letdown to the rest of it.

I've had KSports on two of my cars in the past. That was before i really knew anything other than "Man, these look DOPE!!!" And then, i liked them.

Since then, i've driven another Celica with KSports, and it was OK. I'm not sure that i'd want to do much other than street driving with them.

In terms of what i've compared my Megans to since i've gotten them on the same or similar platform....

1) 1988 Celica AllTrac w/ AGX and Ground Controls
2) My same 92 Celica w/ GR2s and Eibach Sportlines (Eccchhhhhh)
3) 1990 Celica w/ Yellows and Ground Controls

Combo 1 wasn't bad. However, i'm not sure how direct the comparison is. It's a heavier car, and i don't think the spring rates were as high as i run. I played with it a little on back roads, and it felt good, but a little soft to me.

Combo 2, Sucked. Moving on.

Combo 3 was very similar. However, i felt that the setup was under-damped. It had a double bounce going on, and when you would level out from a really hard turn it didn't settle as quickly. It also understeered.

Another point to bring up which may completely throw out all my thoughts is that i run far more tire than any of those did, and a higher rear spring rate by a rather wide margin.

Now, i'm no suspension guru, and i haven't had a ton of time for development on my car, i just go with what feels right. It was bought as a non running shell about a year ago and it's been a long hard road since then to get it to even where it is right now. I haven't corner-balanced it, haven't dialed in what settings are the best yet, i've just driven it and actively tried to upset it, and i can't, due to other limitations of the car. I've just been trying to make sure that all the work i've done hasn't left any stones unturned before i tear it back down again this fall to finally put some power to it.

So, i'm completely open to the fact that they may be considered crappy. Besides my personal anecdotes on them, the only other thing that i have to offer is that i've met a few people that absolutely hate KSports and would rather walk than own a car with them installed, that have no problems with Megans.

I got mine for $850 shipped due to an order error. When they become the weak link, i'll look into something else.

I'm located in Indianapolis, by the way. If you're in the midwest (can't remember, sorry

) i'll be up at the Tire Rack event August 22nd providing my motor holds together.
