R3 parts into "normal" Proton

[g88]

Since R3 is using stiffer chasis (stiffer then Putra, SGTi ??)....therefor i assume R3 engine mounting, arm bush is stiffer as well ??

My question :

IF i am driving a Proton 1.8 model (either Wira, Putra, SGti) with is using C99 chasis (already stiffer then 1.3/1.5/1.6)....can this "normal" Proton withstand the stiffness of engine mounting, arm bush from R3 ??

Will it give any side effect ??

Pls kindly share your view...

i think not...but to be safe better ask the R3 personnel in charge better...

can...it can fit.

but the stiffer chasis is because mainly of the welding done to the chasis.so..changing the other components wont really do much diff.

but u can go ahead unless u will still like the slight change/improvement.

yeah, yeah right. the chassis is cross-welded - meaning double than standard.

it makes the chassis stiffer by means of minimising metal twist.

the result is apparent during real world drive.

The SR3 chassis is no doubt stiffer than the Putra, Wira 1.8, SGTi in stock form due to the spot-welding. I believe there was a small batch of homologation rally-spec Wira 1.8 PERTs which had seam-welded chassis as well. The stock engine mounting on the SR3 is the same as the ones found in the shared C99 chassis models. I would recommend just changing 1 engine mount, as I did with my SR3. This applies to the rear engine mount (near the firewall) which helps in reducing engine pitching (forward/backward movement). Changing all 3 to stiffer mounts will be a real bitch to drive daily, as NVH would be quite unbearable. Undulations on the road would transfer vibrations to the cabin. Unless you want to hear every squeak, rattle and roll in the cabin, I'd suggest you don't have overly stiff mounts.

Stiffer bushes will cause the chassis to be more sensitive and responsive. By simply changing the arm bushes, you will see quite a substantial difference in handling characteristic and performance.

I used to drive a Persona 1.8 sedan before my SR3 and ran SuperPro bushes all round. Feels very, very different from stock. Almost like buying new suspension. No kidding.

So to answer your queries, yes there will have side effects if you change the engine mount and arm bushes. But it is a positive move, not a negative one. :) In the end you get a more communicative chassis and better handling overall.

Hope this helps!
