4g15(Wira) covert 4g18 stroker kit

Oops. Racetech.

I didn't know Kheng Siong was selling foam. And you're right, the Sylphy has very good NVH. But that was when it was on 195/60/15 Yokohama Decimal dB tyres. Now that I'm using 215/45/17 the tyre drone is killing me. Will get in touch with KS and see what he can do about helping. The sound proofing is already done in the wheel arches of my Sylphy and it comes stock with the car. I don't want to do anymore than what's already there. I definitely don't want to add extra weight to an already heavy car with all that soundproofing material. We'll see how it goes.

Hardtech?

Bro., save on your sound proofing, since you mention it was good on 195/60R15. 215/45R17 are performance tyres which you wanted earlier until cannot tahan the drone. Just switch to Yokohama db V551 215/50R15 should be okay dy. Get back your comfort and quietness.....

Probably now he get a "hard" on.....hhahahhahahha

the infamous "midlife-crisis"

My wira is stock 12mm. Measured it a few days ago. The Preve's rear ARB was previously uprated to UR 19mm unit. Feels firmer but not too uncomfortable. Preve is a much bigger car. Hence I wonder what 19mm will do for the Wira.

This references Genting's recently added speedbreakers. I did slow down for them. Even at slow speed, the car bounces over them.

Thank you. :top: Earlier on, I was in a dilemma whether to get FTuned coilovers. Earlier today, one of the rear arbs was going 'nyek nyek'. That coupled with your above comment sealed the deal. Will decide on rear ARB's size after consulting Farouk. BTW, stock 1.8 not as spongy as other Wiras.

LOL .. I certainly can relate to that

Thank you. I think I will do just that. I don't know what the stock spring rates are for a Wira 1.8EXI but I suspect both front/rear are in the 3-4K region. Your recommendation for front 4, rear 3 sounds right.

I have already foamed my undercarriage, ABC pillars. The side sills were done with the harder track foam.

As for SP, I DIY most of it. Hood, trunk, doors, floor and roof. Unless you are very much into ICE, IMO the floor can be skipped. Floor has plenty of ridges/ribs. Plenty stiff enough. For a while, I drove around with the carpets stripped. With or without carpets, the noise level was about the same. At most, if your floor is transmitting some vibration to your feet, get some soft underlay for it. Did the roof not because of noise. Was because it was akin an oven in the afternoon. When I had my roof replaced years ago, I think they left out most of the older insulation. I can get into the car and drive to my destination which is 30 minutes away. By the time I get there, car was still hot. You wont want to be caught in a jam. No need for expensive or heavy SP materials for the roof. Can use the cheaper Insuflex. Fixing the roof and doors will block out a huge portion of our Malaysian heat.

well seems like u have almost all area covered...about heat inside the car....i would blame the glass part....even if u got tint those cheap common..it doesnt help reduce any heat....on my other ride using raytech....it was great..fast cabin cooling and even in dead-heat sun....inside of the car after left parked for long time wasnt that hot to begin with... its just the front windscreen didnt have any tint contribute most of the heat....


so your suspension still in stock form...i believe if u want to remain that way, u can get the apm performax yellow.... for adjustable suspension, get the one with adjustable damping and bodyshift type.....so u can seat the spring just enough for the spring not to jump out of the spring cup/seat and independently adjust your ride heigt.....


as for the room bar...what in my mind tells me for anybody who wants to install it, get it a step further...weld some bracket in the middle of transmission tunnel/chassis tunnel/exhaust tunnel and secure the bar using the front seat rails mounting point....that should prevent this happen.. (the bar folded when subjected to side impact) or perhaps can ask UR to create their room bar version 2 with that additional bracket

#this is where the room bar folded after impact...with extra retaining bracket bolted at that point, it would strengthen the bar for better benefit....

The girl passenger and drive survived that crash. And from the post mortem it really did look like the bars were the only thing that saved the 2.

But uncle pass it and still on rock solid suspension and 45 series tyres woh!......hhahahhahaha

Wow! but was it specially fitted, like extra mounts, brackets etc?

 

[Izso]

nope. That Satria had all the standard bars that UR have for sale. That GTI is owned by the UR salesman la.

This unker speed different case.

 

[parakey]

I am a bit puzzled. How is it 'room bar' is legal while roll cage isn't?

When I look at the above pic, I don't think I want to sit in the rear. In the event of a front/rear collision, and the rear passenger isn't belted properly, what happens to their legs?

thats why it needs additional bracket to hold it firmly and not crumple easily

Gotta hide that room bar under the carpet so that parents don't catch me modding my car.

 

[parakey]

you plan to change your suspension first before touching the rear arb?

Yes. I want to gauge how much the car rolls after installing the coilovers. Then decide how thick the arbs should be.

In case anyone misunderstood my earlier sentence, I meant to say "forget the rear tower strut bar if you are going to go ftuned coilovers".

Lol .. I had to read that twice before I understood.

you mention it was good on 195/60R15. 215/45R17 are performance tyres

vr2turbo's analysis is spot on. How come he's so familiar with your car? Must be parking right next to you. :cheers:

Upsizing by 2X makes a lot of difference. On the old tyres, the thicker 65 profile cushions the road vibrations. Not that much gets transmitted into chassis. With the much harder 45s, your chassis speaks to you in an angry tone. Can you feel it via your steering?

That's why I mentioned SR/RaceTech chassis alignment kit helped with the wira. Without them, a lot of vibrations gets transmitted back into the cabin.

as for the room bar...what in my mind tells me for anybody who wants to install it, get it a step further...weld some bracket in the middle of transmission tunnel/chassis tunnel/exhaust tunnel and secure the bar using the front seat rails mounting point....that should prevent this happen.. (the bar folded when subjected to side impact) or perhaps can ask UR to create their room bar version 2 with that additional bracket

Why don't they design the room bar to be placed right in front of the hump of the rear seats? That way, the bar won't be in the way of the passenger's legs.

Sounds like a plan. Why not? Whereabouts do you stay? Let's PM. I'm curious to know about pricing of foaming.

Remember the mamak I suggested in the ZTH Cheras thread? I live nearby. Anybody else wants to take a peek? Specially those entertaining the thought of foaming their rides.

Get adjustable ones!

Aren't FTuned units adjustables? Think they are nearby your home.

Adjustable anti roll bar is not adjustable suspension wor. Do they do anti roll bars?

They are making adjustable suspension. Also sells UR bars. Here's a link to their site > http://www.ftunedracing.com/index.php?option=com_content&view=article&id=7&Itemid=13

Local unit. A bit like RCS; lotus trained.

I know. Aha. Not sure of their UR bars are adjustable. I do know you can get em made at UR themselves though.

Ah, I see now. I must have caused confusion when I said .. "gauge how much the car rolls after installing the coilovers. Then decide how thick the arbs should be".

Actually by "how thick" I meant choosing between the 16, 19 or 23 which UR currently offers. Currently thinking of getting 19mm but if new coilovers with stiffer spring produces less body roll, then will settle for 16mm units.

Actually it's when i said get adjustable arb and you mentioned ftuned. :slug:
How much is it eh?

 

[parakey]

How much is what? If UR ARB, I see 16mm listed around RM300 and 19mm around 4xx. Was looking for used units but couldn't find.

If FTuned, they list their price for Wira here > https://www.facebook.com/media/set/?set=a.794557920581305.1073742001.209466972423739&type=3

Oh damn that rear ARB is cheap. The suspension is also below my expected prices. Seems like cheaper than Titan wor. Ftuned is supposedly custom right?
