suspension suggestions

Been on here a long time but was always a MK1 guy. Thinking about a MK2 with 2GR. Car will be a toy occasional daily if that makes sense. Want it to handle well of course but also have a decent ride. The last stock late MK2 turbo I drove rode kinda rough for stock. My MK1 had Tokico Sport, ST springs, and TRD bushings and strut mounts. Would like it to ride better than that without braking the bank. Will not be on a track. Does not have to be coil overs.

Whether you own an SW20 with a 2GR or a 3STGE, Koni shocks and '93 springs are a smart choice for a track worthy ride yet have a comfortable ride quality for you (& your girl).

TRD bushings still aren't a bad idea though, they're slightly harder rubber than the OEM versions but they provide a less harsh ride than poly bushings.

Is this your car? If so where is it located. Do you have more pics? Has the ecu received Gouky's reflash for rev limiter and low rpm torque production?

1 car in particular I am looking at started life as a '93 turbo. Why do you mention '93 specifically? Are there any aftermarket springs that will ride well but handle good too? How are Eibachs for this?
Most likely wont keep factories size wheels/tires. Already finding that the stock sizes, especially the rears, are that common. Looking at 215/45-17 front and 235/40-17 rear.

The '93 springs sit the car a little lower than the '91 springs - it's not much but it's a noticeable difference.

The Tanabe GF-210 springs are similar to OEM but lower the car about an inch. The Pro-Kit is a popular choice, but I wouldn't get those springs without mating them to Koni shocks. If you want a bit lower still, there's TRD (hard to find) and/or H&R springs, both high quality springs but definitely a bit lower than most.

As for wheels, 17s seem to provide the easiest compromise for handling & comfort. Wheels in lightweight +30 to +35 17x7/8 (215/40-17, 235/40-17) or slightly heavier +35 17x8/9 wheels with similar tire sizes work on the SW20. You can fit wider 235/255 tires on the 8/9 combo w/ a slightly lower wheel offset up front and slightly higher offset out back.

regardless of springs I will most likely go adjustable Konis. It was my next choice for my MK1 when I had it. I like the idea of the Eibachs. I don't want to go real low or real stiff. Roads in southeast Louisiana suck and seeing how I want to actually be able to daily it to a point I need it to be somewhat comfortable. My MK1 with ST springs and Tokico blues could get tiring after a while especially on rough roads. I would like this car to be used for weekends with the wife. One, of many, thing my wife hated about the MK1 was that it road so stiff.
I don;t think there will be a big need for huge tires for grip at the power levels the car should have. The sizes I mentioned are fairly common too price shouldn't be too bad either.

If your wife's comfort is truly a concern, then stick with OEM 93+ springs and Konis on full or nearly full soft. Don't get cheap, heavy wheels - that will degrade the ride as well. Consider a 16" / 17" staggered wheel fitment. The taller sidewall (of a 45 or 50 series) and generally lighter weight wheel in front will also help ride quality. The BFG G-Force Sport CompII offer 205/50-16 and 245/40-17 sizes that work well on a 16x7 (or 7.5) and 17x8.5 double staggered setup. Very good tires for the price.

Excellent advice, Jim - especially the light wheel stuff. Too many owners overlook it because they cheap out on the cost of them (usually forged) - ya gotta pay to play.

The ZII from Dunlop also sports 225/45-16 fronts for a cushy ride too on double-staggered combos.

One other thing to keep in mind is, if you really want a good ride you can't lower the car too much.

Soft springs with a large drop will ride great until you hit the first bump, which slams you into the bump stops. If you really want to lower the car an inch or more, you are actually better off with a little bit stiffer springs. You will end up with a firm, but hopefully not jarring ride that way.

I have Koni adjustables with Eibach on my 93 rolling on 17x8/9 Enkei RPF1s. On stock wheels the Ride was nice, but after putting the bigger tires on, the rear would rub just a hair. To fight that, I set the Konis stiffer and of course the ride suffered.

My wife's 94 is on stock springs and non-adjustable Konis. Those with new ball joints and tie rods made her car ride like a dream. It's a little high for my taste, but I do love the ride. She is on double staggered 17x7 / 18x8 Enkei EKM3s.

On a side note, my car has Yokohama s.Drives and they have been fantastic.

Just a bit of a sidetrack item: When I did my 4th gen swap I noticed a few of the bearings looking a bit worse for wear at the back. I couldn't find rubber items, only prothane at the time.

You guys mention TRD being somewhere in between oem and the poly stuff - is it available anywhere?

I have a complete set in my parts bin I haven't gotten around to installing, but I haven't seen them for sale in many years - maybe half a decade or more.

I have a 2600lb mr2 with a 2gr on koni yellow and eibach pro kit springs. I also have a front TRD bar, the ride is pretty good coming from 10 years worth of owning coilover setups. Handling is ok, its not a very competitive set up. It works to have fun with but don't expect to have it keep up with newer cars. The springs are way to soft, with yokahoma S.drive it already maxes out the springs. And the S.drives are not exactly what I would consider very high grip tires.

I didn't know you can still get trd bushings.

You can't, unless you can source a place that carries NOS (new old stock).

Ok, 1st off thanks for all the responses. Trying to learn as much as possible about MK2s before buying. The last MK2 I drove was a then new stock '94 Turbo. On the interstate I found the ride to be pretty stiff especially for stock. Not sure if that was from the springs or shocks. I'm guessing the shocks. I was shying away from 16s due to lack of tire choice. I would really rather have 16s as I like the look better than 17s. Dont care for 18s on a m2. Not looking for a "competitive" suspension. This car will be a weekend toy/part time daily if that makes sense. I would like to be able to drive to work, aprox 90 miles round trip, without killing my back. Almost definitely going Koni adjustable. Never used them myself but have read nothing but positive about them. Also not concerned about competing with modern cars. Honestly my '86 with TRD bushings, stock '85 rear bar, ST springs, and Tokico blues would out handle most new cars and that was with stock 185/60-14 tires. Not looking to lower the car a lot if any. Also not looking to run steam roller sized tires. Don't feel the car will need them and don't want to worry about fitment or availability.

Does anyone have pics of a stock 93-95 on 16s or 17s or staggered? Would like to get an idea of how they look.

Pretty easy formula:

  • '93 springs
  • Koni yellows
  • 16x7 front, 205/50-16
  • 16x8 rear, 225/45-16
  • Tires: Direzza ZII Star Spec

This is a '91, but you get the idea. First is on stock springs, second one is the Pro-Kit.

Nice car. Did the Pro Kits even drop the car any?
How much lower are the 93+ springs than the 91-92?

93+ springs drop the car about 1/2" from 91-92 springs. The Pro-Kits I think are about 1" lower than 91-92 springs. Even if you can't find a used set of 93+ springs, you can buy new ones from a discount Toyota dealer for ~$250 a set.
