156 GTA Coilovers!!

Just out of interest. Are we sure the Intrax version is exactly the same as Autodelta Corse? I know the dampers are but doesn't autodelta have got special tune springs for GTA. The photo shown on Autodelta website has different colour spring between front and rear.

One thing put me off from Intrax is they stated the same p/n for 1.6 to 3.2 156 engine. However Autodelta only use it for GTA and they have different coilover for non-GTA 156.

You will need to check with Jano about the length of warranty, its at least one year I'm sure.
Generally there is no quibble on return of parts, only issue is shipping from Oz is expensive so I guess it would be good to confirm that they would bear the cost if you had to return a damper due to a fault, once they had verified the fault.

Generally they would want the damper returned, before shipping a replacement.

I wouldn't think there are many faults with the Corses though, they look extremely well made, and mine have had two years of very extreme use (and Irish roads )

Personally in your situation I would go for the 8Kgs, but if you really crave comfort then perhaps its worth giving Jano a call and talking to him about the 7Kgs :-)
Hes normally happy to discuss this stuff in practical terms - hes very approachable and easy to talk to on the phone.
Whatever you end up getting spring wise make sure you get the adjustable damping (Corses) anyway!

Obviously the time zone is a bit of an issue for you so heres a tip:
When you dial AD option 3 is to talk to Jano, so try this.
..but if hes not there, you can hangup, dial again and dial whatever number it is for parts (its says it on the message).
This will put you through to Ken who would be able to tell you when Jano would be back, or if hes out of the country etc.

Cheers,
TB

I don't think I will track my car. I most do normal road driving and have a stretch once a week around the mountain. Comfort is essential for me (and my missus). I do like the ride comfort on standard GTA suspension on even road but I don't like the body roll from stock suspension.

My car is stock standard that I even sold the ASSO carbon pipe that I had for last 2 years and now return to stock standard except the Alfa front strut bar, Q2 and 330mm upgrade. Therefore my car don't have any extra power.

Do you think I should just go for 7kg or 8kg since you reckon 8kg is comfort enough?

Also what is the warranty like from Autodelta since I'm in Oz.

Great info TB (as usual )

Gents,
Even though Intrax "could" be supplying AD, they are usually made to a spec that is special order & cannot be supplied to anyone else other than in this case AD.
I'm not sure but on an E46 M3 that I had, I fitted an AC Schnitzer coil over kit which at the time being BMW approved would not void the warranty. This kit was made for ACS by Eibach, from my info.
I suppose it's the same for many of the big name tuners, they develop a specific component in partnership with a company that specialises in the said items, whether that be coilovers, LSD's,clutch kits etc. We all know that the AD superchargers are Rotrex units but Rotrex don't do a fully bolt on comprehensive kit for an Alfa as do AD?

IMO AD are the best choice as they have what seems to be the largest market share as far as modded GTA's go, thus the experience to supply a package that works.

That said, the GTA's that raced in the production car class in SA ran their 1st season on KW's, then they followed another route. AD was mentioned.
Ciao

It does make sense in this way.

ABYSS,
You may be interested to know that with the AD Sport Corse coilovers I use Eibach adj.roll bars front & rear, AD heavy duty front arms & Orque Racing Japan rear adjustable control arms. Of late front upper & lower strut braces as well as a rear brace have been added but I haven't driven the car in this form. I'm leaving for SA tonight so I'll try the car out soon & see how it works. The wife told me that the car felt much stiffer, more solid. Lets see?

What should interest you is that I told Jano that I was running 19" OZ Superleggeras with 225/35ZRX19's & he fitted spring rates that in his experience would suit road & occassional track use. We played with the 40pos settings but on his recommendations. He gave us a base set up & then the car was cornerweighted, set up & tested on the road & we now have a good compromise I think.
I will however have to do that exercise again when I move to Greece in 2008 as conditions are different but then again AD have a dealer in Athens & are well versed in the local conditions.
I think that the set up of my GTA's shocks would be ideal in your case as SA & OZ have virtually identical road conditions & climate. What make of tyre do you intend to use?
Ciao

Thanks for info Monstro. I don't know whether the road of SA & OZ are identical but speed limit will be definitely not. If I travel more than 20 km/h than the speed limit I will loose my license straight away.

I'm using my 2nd set of PZero Rosso. I know it might not be the best but I like idea to have italian rubber for italian car. Part of the reason that Autodelta interested me is somehow Alfa related brand.

I agree on the tyre issue as I've ordered Pirelli PZero Corse to replace the Yoki's.
I understand about the limit issue as in SA there are far more oppurtunities as well as empty roads to hit some serious speeds, especially in the Cape. Johannesburg/Pretoria is so congested nowadays that maybe an odd burst traffic allowing & no rozzers(they have 90% of the rozzer popullation) around to say 180-200km/h.
In OZ I've heard that the traffic cops are draconian????

To me it's not speed that kills but speed under the wrong conditions, under the influence, being reckless...............
BTW what is the official national limit in OZ?
Ciao

Very interesting thread.

I am also looking into coilovers for my 156 GTA.
After reading all the info discussed here I will also go for the AD fully adjustable set-up. It sounds well worth it.
Monstro has offered me his AD brakes (they will compliment the suspension nicely) at a very reasonable price once his MOV IT's arrive in January. (Thanks again Monstro)

By the end of next year I should have one well sorted GTA.

GTAMad,
I'm in SA tomorrow & after recovering(during the weekend) I will immediately contact MOV'IT & see where they are with things. As discussed before, if they send the kit & it lands up at SA customs after Friday 14th there's no chance of seeing the bits until the New Year as its the annual shutdown period for Summer/Xmas holidays, nothing happens.
You will be happy with the Alfa/Autodelta 330mm kit but I will send you both the standard road pads as well as the competition pads that Autodelta supplied with the kit. The AD ones are very noisy & it irritated the s...t out of my wife, even Dawie when he fitted the stage 4 heads & cams, whilst covering a couple of hundred k's testing the thing he went crazy from the noise around town but hell, do they work.Good thing is that I have the Xdrilled AD rears as well, including all the brake lines so you have a full on 4 wheel kit.
BTW, Dawie is battling to get the 3.9L set up. His had Peter De Weet(Dastek MD) at his place with a laptop trying to sort it out.I've always done incremental changes starting with a stage 1 3.7L(with the steel bottom end bits) & then upgrading heads, cams, TB etc in stages.
We added so many things at once to the 3.9L & wild heads, wild 12:1+CR, 304degree cams, bigger TB, intake,injectors......................well the amount of vacuum variance in the plenum is playing havoc with the drive by wire system, now they are testing the latest prototype Unichip called the XS, apparently its able to trick the ECU when you run really wild s...t!!!!!
Lets see what happens.

Sorry to hijack the thead guys, so back to the coilovers. Jano told me that I didn't need the Eibach roll bars with the coilovers but I've found them to be an asset.They are 2 position adjustable & I set it up at the stiffest setting for a track day, it's really easy.The car is straight as an arrow at 220km/h+. They are fantastic.

I've heard various opinions when it comes to camber settings. The race GTA's in SA ran around -5deg camber, I've had my roadcar at -2deg, 0 at the rear.Anyone tried something different? Whats the feedback?
Ciao

It's actually the other way around, bottom of damper for bump, and top of damper for rebound. Yes, you do have to lie on the ground to adjust bump, and that can be inconvenient or even impossible depending on conditions and state of dress

The upside is that you get more "tweakability". The Thorney paper below highlights some of the benefits.

http://www.thorneymotorsport.co.uk/c...nsionsetup.pdf

Also rebound settings have a much greater effect on comfort than bump settings do, so a lot of the KW3 users leave bump in their preffered track setting, and simply adjust the rebound for road comfort.

BTW just got email back from Autodelta. He said the default spring rate for Corse is 70/220....

Hi Monstro,

can you give some more detail on the AD heavy duty front arms?

Cheers,
TB

TB, could be polybushed perhaps..........., but I guess Monstro can answer for himself. Just a guess.

Over to you........
