Those with Megan Racing Track Coilovers PLEASE HELP

[CyFi6]

I have recently bought some megan racing coilovers, ive been having some issues. I have the stock wheels/tires on my 87 supra, and the rears are locked at their lowest possible setting and i still have a wheel gap. Have you guys noticed the rears dont go very low?

If possible can you take a picture of the rears and fronts with the wheels off/weight off the suspension?

On my fronts, the threaded tube is extended out much more than the rears and the springs on the fronts seem to compress a lot, with the same fender gap on the front and rear, if i raise the car up the front wheel gap gets much much bigger to fully extended than the rear gap gets, telling me the spring is actually compressing a lot more on the front.

It seems as though its compressing too much almost. When i bottomed out once it felt like i bound the spring up (maxxed it out) before i hit the bumper on the damper.

Please let me know if you guys have seen any of these issues/post pics please as i am confused.

AF1JZ has a set I believe. Hopefully he will chime in here. If not, PM him a link to this thread and ask him to give you some advice.

Many people have the issue of not going low in the rear.

 

[BlackMKIII]

Funny, I have the same issue with mine. I was actually considering disassembling them and chopping an inch off the threaded tube.

Might not be wise, though. Ace (Grimsta) once told me that you can compress the spring, but I've maxed it out in all directions and can't get my fender lower than 25".

 

[BorHor]

Throw more stuff in the rear

 

[Stanzaspeed]

I have the same problem with mine. I just plan on selling them to friend and buying something different when the time comes.

 

[AF1JZ]

I have them on mine. I'm not having that problem with mine like you guys. If you look at Boris' (Borhor) thread on the lowest DD Supra, youll see where my car sits with 18's. I also have two in inches in the front and an inch in the rear left to lower. I'm not sure why you guys are having problems with lowering it more.

Only thing I can think of is how it was preloaded when I put them on. I put it on the softest setting before I lowered it off the jack stands. I read it somewhere before i put them on. So, I gave it a try. I will tell you that it was a pain in the ass to adjust them even with the wheels off.

I forgot to ask you earlier, but I'm assuming that the shock is bottomed out in the lower mount. And you said you're running close to zero preload right? If so, the only way to get lower is to use a helper spring and intermediate perch or droop the spring which I don't really recommend. I think this is what I said in the other Megan thread.

How are other people's cars in this respect?

The only threaded part that you could cut that would allow you to go lower is the shock itself. And I highly recommend NOT doing that. The car will handle funny and you'll have shock fluid all over everything, it's just really not a good idea.

As for compressing the spring, that would only work if you have a lot more room to lower the shock into the lower mount. But that doesn't seem to be the case. And if you did have more room to lower the shock into the lower mount, you wouldn't want to add all that preload just to get the car low.

 

[CyFi6]

I did inspect all these parts before i put it all together. You cannot cut the bottom of the threaded part as it is part of the damper as stated above. However, in the sleeve part, with enough effort, you could make it go lower. There is a larger diameter cut down the tube where it allowes the shock tube to go in, but near the bottom, probably about an inch or 2 above where it starts to taper off, there is a lip, this lip i believe is what stops the thing from screwing in any more. If there was a way to somehow get something in there to grind that lip away, you could easily lower the car a litle more. The only idea i had was finding a hole saw the exact size of the inside of the sleeve and extending the part for the drill so it could reach way in there and cut through this lip. If there is a hole saw the exact size it would work in theory.

It would be wonderful if you could get a picture of the rear next time you take the wheel off.

Sell your Megans and buy my Cusco's(800 shipped). You'll probably come out even.

But seriously, many have had problems with the Megans not going low enough as you can see in this thread. The spring bottoming out is because, I think, of the spring rates. They are the highest spring rates on any coilovers for the MK3. They are something like 19k and 12k.

Im happy with the height the rears are at, if i would have set it i would have done that anyways, but it just seems like it should be able to go lower.

Also, can you explain to me what youre talking about with the spring rates? Why would a higher spring rate cause it to bottom out on the spring, cause its thicker?

I'll give it a try today if I get off early.

Tim: Sounds like incorrect Body/Spring lengths?

 

[Wiisass]

In all honesty, it sounds like too modular of a design and cutting corners to produce a cheap product. If they can't get the damper lengths right, then what would you expect of the valving.

Cyfi6, I'm not sure what Ben is talking about. It doesn't really make much sense. What are the spring rates on the megans? 18/12? A stiffer spring won't bottom out, as long as everything is setup right, meaning preload mostly. It takes a lot to compress a stiffer spring to the limit of shock travel or spring bind.

Yeah I'm an idiot and it was way too late to be typing technical stuff like that....

I need something in my sig that says "Whatever I post might be totally wrong."

It's cool Ben. I went ahead and put it in mine so everyone can see

 

[CyFi6]

when going over a speedbump where the front as a whole bounces up and down it feels like the springs are compressing fairly easier than i would expect

LOL. Look at my sig, then go check Dunckel's. :biglaugh:

Actually Megan Track Specs are 18/14. :aigo:
