Suspension help

Post by zooplane »

1. Thinking of lowering with H&R or Eibach... which is better?
2. If I get springs, will i risk the life of my stock shocks? If so, what shocks do I get?
3. Going for 18" Peg replicas with 235/40/18 and I'm planning on getting a camber and alignment adjustment following...
4. Any other ideas or suggestions?

Thanks!

I went Eibach they only lower your wagon 1.2" H&R go about 1.5"-1.6" and Eibach are progressive spring so when you are just cruising they are still comfort to them. The lower you go the stock shocks will not be able to work in the manner that it was designed for the strut/shock will bottom out. I went stock struts/shocks and Eibach springs and everything works great and love the look! But if you are still worried or go H&R Bilstein makes a great strut/shock and are made for lowered car/wagon.
So 18"or 17" or I should say 40 series to 45 series tires? Again it's a little comfort or a little bit more handling and a little bit of handling compared to the difference of comfort, I went 17" 45 series.
And I went IPD sway bars and upper strut bar, WOW what a difference my wagon is awesome! I hope this helps...

I'm now thinking of going with the Koni FSD sport shock system with H&R springs... will this give me a good ride AND good handling?

Also... I've heard that going with bigger rims on a non turbo and low HP car like mine puts stress on my transmission and engine... Is this true? I'm thinking of sticking with my stock 15's if this is true...

Yes Koni & H&R is a good combo, it will definitely give you a good handling wagon! when the road is smooth your ride is smooth, but with any stiffer strut/shock and spring combo you will feel the pot holes, bumps and all the other road imperfections.
But those on ramps, off ramps and winding roads are so much fun! On that note I've have not done that combo (Koni,H&R)
Every car I've owed I've have modified and love it and the trade off from harsh ride to comfort is a fine line, but in all the suspension mods I have done I found that going to a taller series tire really made a difference in comfort.
As far as bigger rims on a non-turbo compared to a turbo I have not heard that one ? Lat me put it this way say your 15" rim and tire over all circumference 23" (edge to edge/top to bottom) and I think your tire size is 215/65x15 so plus 1 would be 215/55x16 plus 2 would be 215/45x17 plus 3 would be 215/40x18 all be it the width would more like a 235 but anyway so the over all circumference is still around 23" so I've done bigger wheels with no problems, but keep in mind the plus 1, plus 2 thing. And yes you can put more stress on your motor/trany but that's because your pounding thru the turns a lot harder and putting your foot into it coming off the corner! But what I think people are talking about is that the V70 is a front wheel drive uni-body wagon so you can get body flex witch in turn will put stress on your CV joints to the transmission, motor mounts ect. That's why I did the IPD upper stress/strut bar it made a box like section in the front suspensions the theory behind that is that it holds your front end in alinement.

Hey thanks a lot for your full explanation! A couple other quick things...

1. So basically as long as I keep my total edge to edge distance the same when upgrading wheels and tires ill be ok without bottoming out?
2. What are taller series tires?
3. I'm thinking of doing 18 inch pegasus replicas from IPD and 235/40/18 tires... and people are telling me that my whole suspension, camber and such will get thrown out of wack...?
4. I have an upper engine strut brace that came with the car and a rear anti sway bar that I just discovered... so that will help when I upgrade my suspension...

So tire size yes think of it this way say you have the tire/wheel off your car and you take a measurement from the ground to the top of the tire and it's 23" (23" is just an arbitrary number but I think I'm close) and that the whole thing with plus 1, plus 2 is
That you go up an inch in wheel size you go down in tire size or series.
So tire sizes go like this 235/40x18 (235= 235mm the tire width) (40= 40% of 235mm is the side wall height) (18=18" the rim size)
If you where to go 17" rim your tire would be 235/45x17 and so you keep that over all circumference.
What will thrown your camber out of whack is lowering your wagon and that's why they make camber adj. bolt kits.
The only way wheels and tire combo's are going to thrown your camber out of whack is if you went like 235/55x18 and you over all circumference is like 25". And think about it a V70R comes with the wheel/tire combo you want...
Once you do all this work you will need an alignment witch the shop will put right to the factory specs. But you just might want the camber bolt kit with the H&R springs because they do drop your wagon over an inch and a half?
And this whole tire size thing as long as you are close like 23-1/2" or 22-3/4" or so it's all good.
Your not doing like what that kid on your block did to his Honda and cutting your springs 4 coils and dropping your car 3" or like your neighbor with that Chevy truck and he dropped it 3" but he used dropped spindles to make it all work.
So in short what you are doing a lot of others have done it too! (Me included) And the whole thing with tire series is so that you do keep that circumference you need.
Okay that upper strut bar or what looks like a upper strut bar is actually your upper motor/trans mount and bar.
A V70 is a transverse front wheel drive uni-body wagon, so it has a right motor mount a left trans mount and a upper mount that keeps the whole motor/trans from rocking in the engine bay. IPD does make a kit to make that mount solid. But I've heard that you feel all the motor and road vibrations in the steering wheel?
And I have to say the biggest wow factor I got was when I did the IPD sway bars they really made a difference and I to have a rear sway bar that came that way from the factory. IPD's are bigger (bigger is better) and poly bushings and they havr HD end links the list go's on and on!

Thanks!! The only thing is that my car came with 15 inch rims and 195/65/15 tires... thats a total diameter of only 17.5 inches... does that mean the biggest i could go is 16in rims?

You can run whatever wheels will fit!
With those 18s (235s) you probably WILL rub like an R does
You will need to adjust or buy longer steering stops and/or use 5mm spacers in the front
Maybe a 225 would be a better tire for you
