Astra coil-overs fit North American Daewoo Lanos?

[ash169]

First off I should introduce myself. My names Ashton...I live near the West Coast In the US. My boyfriend and I own a Lacetti, a Lanos, and a few other cars we don't use/drive right now because I started going to school so we don't have the income we used to.

Anyways, I've been wanting coil-overs for years now. I almost didn't even buy my Lanos because I wasn't able to find any great sport suspension stuff available but I finally bought the Lanos couple years ago because I knew there were other vehicles that shared the same suspension.

When looking at different Astra and similar coil-overs I noticed some are for 2.0 and some for smaller (therefore, lighter) engines/transmissions. My Lanos came with the 1.6/D16 but I have a 2.0/F28 waiting to be put in once we finish redoing the interior in our Lacetti.

I plan on doing track days with the Lanos and it is a daily driver. I'd like adjustable coil-overs (the more adjustable the better) and have been drawn the the KW coil-overs because I have them on my Lacetti. Also my lanos is lowered 50mm f/r with lowering springs now so the coil-overs need to be able to lower my Lanos at least 50mm f/r from stock but preferably much much more... I prefer to have the tires tucked in the fenders.

The only other thing about my car that I can think of that will effect fitment of coil-overs is a rear disc conversion I'm slowly gathering parts to do this year.

So if anyone could tell me what makes/models and which years/trims share the same suspension or should share the same suspension please let me know. As well as what is available for that car as far as coil-overs or a good place I can start looking for them. A recommendation on where to buy would also be appreciated as finding English speaking sites that ship to the US wasn't always easy to find when doing my research.

Also since I'm posting about where to find things I'm also looking for a few other things like a great price on a qualife LSD for the F28 and D20 (I can get them here but am hoping to find a better deal). Any other suspension mods like bushings, sway bars (anti-roll bars), strut braces, lower control arms, anything to help bump steer with a lowering.

A few other things I'm interested in is a quick shifter (the linkage, we already have a shorter stick), where to find shift knobs that work with lift up reverse (other than Isotta), roll cage, seat rails for bucket seats, stronger/lighter drive axles, A pillar gauge pod, and those kinds of things. I guess I'm always looking for anything OTHER than engine, transmission, and brakes related things because I either have those or know where to get those things.

Thank you very much for any help you can provide me.

Re: Astra coil-overs fit North American Daewoo Lanos?

I guess I should add exactly what Lanos I have and everything...In the USA there aren't many differences but I know there are Worldwide. It's a 2001 Daewoo Lanos S 3-door hatch 1.6L 4cylinder 16 vavle DOHC with the D16 m/t. Came stock with front disc rear drums. As far as I know all Lanos' suspension/engine/tranny are nearly the same between all years and trims with the only exception being the Sport has the Close ratio D16. I think a few Lanos' may have came with rear disc brakes. All models here in the US are equipped with an independent MacPherson-strut front suspension and a semi-independent rear.

The only other thing about my car that I can think of that will effect fitment of coil-overs is a rear disc conversion I'm slowly gathering parts to do this year.

I also forgot to finish what I was saying here. I'm gather parts to do a rear disc conversion in the future and these parts include a rear hub assembly from a 1993 Saturn SC/SL/SW series and then using ~12" wilwood rotors and 2-piston calipers

I also would like to add a second rear sway bar as well. It's from a late 90's Saab 9-3 because it uses a very similar rear beam and the sway bar I'll be adding is the external one. I'll probably have to weld mounting tabs for it. Though if I can find a upgraded direct replacement sway bar I'll just go that route of course.

Re: Astra coil-overs fit North American Daewoo Lanos?

they should fit
the mk3 suspension is a little closer to the lanos though...

you should post this question on daewootech.com (I'm on there as "benzino")

GSE_turbo (Garrett) is doing a similar rear beam swap (but the whole saab beam)

I'm trying to work out suspension kit as well at the moment
I'll probably go for spax adjustables (if spax ever emails me back) or bite the bullet and go for koni yellows...

larkspeed.com has the coilovers for the mk2 and will post worldwide (just remember to ask for the invoice without the 20% VAT as you are overseas)

Re: Astra coil-overs fit North American Daewoo Lanos?

i guess i should add the customary warning, suspending the cars weight from a turret designed only for medial load from the dampers. you will need to reinforce the top end of the chassis and fit slim coilovers (otherwise it will rub on the inside of the road wheel) or properely "turret" the rear, welding in wide tube stock. the beam end will also need reinforcing, the area where the bottom of the damper bolts is also not designed to suspend the cars weight.

Re: Astra coil-overs fit North American Daewoo Lanos?

So what year(s) Astra and what trim models will work? and which would be best for me (cuz extra weight on front end and weekend track car)?

and are you positive it will be a direct bolt on?

Can you elaborate on why needing to reinforce these areas? I've never seen coil-overs for a car with the style of rear suspension that Lanos has. Is it because the spring will be mounted with the shock and the shock mounting tabs weren't made for the stress of the spring?

I haven't heard or seen slim coil-overs when doing my research. I'm not sure it'll be a problem though. It looks like I have a bit more than enough room. Currently my Lanos ~50mm lowered and I have 7" wide wheels with 205/40/16" tires. I do want to upgrade to 7.5" or maybe 8" with 215-225mm tires. I'm confident the 7.5" wheels will fit but they're hard to find lightweight and under $400 for a 16" and there are very few 215-225/40/16 track tires or any tires for that matter. I don't mind doing slight fender flares, I already have some fiberglass universal ones and will be learning how to fiberglass this year. I also have a huge selection of 1.5, 3, 5, 6.25, 8, 10, and 12mm wheel spacers I've collected over the years and the Lanos has stronger wheel studs installed because I needed 6.25mm spacers up front to clear the calipers.

Either way none of these issues will be much of a problem. My bf and I just bought a welder too but need many more hours experience before welding something that effects safety. So we're fairly ready for any issues that might arise. If you know of any slim coil-overs that fit please let me know. I'm going to attempt to go with KW unless they can't lower the vehicle enough and are overly expensive.

Re: Astra coil-overs fit North American Daewoo Lanos?

Another thing I'm confused about is when looking at coil-overs on just about every webstore...I'll click "View coil-overs", "Vauxhuall", and it'll list
ASTRA G, ASTRA G-CC, ASTRA G OPC, ASTRA H, ASTRA H GTC, ASTRA H VXR, ASTRA F, ASTRA F-CC lol and I could go on but Im pretty sure you got the point. But then each one will sometimes have convertible, hatchback, saloon, cabrio, lim, coupe, estate, ect which I know some of those are the same. The most confusing part is sometimes in wont have ASTRA G, H, ect but use MK2, MK3 (which I understand) and sometimes it'll say Astra G convertible/cabrio then sometimes it uses only Astra G convertible and it'll all be on one webstore, even sometimes on the same brand coil-overs but different models of that brand. I haven't been able to find anything "official" that even uses G, H, ect to describe an Astra let alone explain it.

So a rough description on what some of these things mean/represent would be helpful.

the rear damper turret is sized to house a 1 3/4 or 2 inch damper. the most common coilover size is 2.5 inch internal diameter, so 3 to 3.5 inch outside. so it doesnt normally physically fit in the turret, and for the same reasons is closer to the inside of the road wheel (especially wider aftermarket ones)

you can get coilovers is 1.9, 2.0, 2.25, 2.5 inch internal diameter

Re: Astra coil-overs fit North American Daewoo Lanos?

If you click here you can see the work that I've had done on the rear of my mk2 to fit coilovers. It might seem a bit over the top but I wanted it to last

Alright, where can I find these? I've found dozens of webstore with coil-overs but they never have much info about them. Just Make/model/year, engine size, and adjust-ability. I haven't seen anything with relocated steering arm pickups or that list the size.

Great read, thanks!

Looks great! I had my bf check it out and he planned to strength the lower mounts anyways...among allot of other little stuff. Right now we're going to do what's needed to get coil-overs on safely and over the next 12-18months do lots of little things to beef it up. We'll probably add a cage as well. But for now the suspension needs replaced, and it *needs* to be lower. lol. It's our furthest car off the ground which is a shame because I think the Lanos is a great looking car to lower. Also it's the only car we have that is registered and not in pieces right now.



I still need the most important questions confirmed. Is the MK3 the best and a direct fit (other than the need of strengthening weak points) for my Lanos?

What coil-overs do you guys recommend? and where can they be purchased or where is a web-store that has a good selection of coil-overs with decent descriptions I can browse?

In the builds you guys linked me to most of you guys get coil-overs custom made by sending in some OEM pieces but we can't have our car not running for more than two days and postage from the US would add more cost.

Thanks for all the help that's been given so far! Cheers
