Mr30, Coilover Conversion

[mr30walker]

Hey SAU!

I have a tricky question to be asked and sourced i currently own a 1985 MR30 Skyline

Before directing me into previous made topics i explain mine is completely different, my MR30 has had a 5 speed RB30 conversion

and i wish to do the s13 coil-over conversion!

my problem in being that the RB30 is alot heavier than any standard sr20, 100kg to fact!

Therefor i have been explained that a standard s13 coil-over (Which usually hold a weight rating of 8kgs at front 6kgs at rear)

i am looking for a 12kg front and 8kg rear or shall 8kgs front and 6kg front be fine?

Help is very appreciated

Ty!

Walker.

anyone?

s-13 conversions are done all the time in r31's....

not to many people think quite that far into the process ie engine weights. do it, see if you like it at standard spring rate, change them if your not happy.

are you going 2nd hand coil overs or brand new, you can at a small extra cost normally get different springs/rates when buying new.

Come to the Classic Skylines Section.

S13 and C210 weigh the same.

Seeing as R30 is a C210 with a newer body on it i wouldn't think they'd weigh much more.

The 8 & 6 springs will be fine.

Yer, i have read about plenty of s13 coilovers into the mr30, and i am buying new coilovers from B.C unfortunately i have not had a reply from them,

thanks for the input rsx84

Socrates the difference is ive put a 250 kg RB30 in it making it alot heavier at the front.

are you emailing BC directly?? find a dealer/re-seller for BC coil-overs, they want your money and will answer faster..

option 1 garage in Brisbane offer both HSD and BC, look around for a more local option

i ran HSD HR coil overs in my R31 (s13 conversion) 8kg fronts and 6kg rear, standard spring rates off the shelf. for a daily driver they were stiff but fun.

i also fitted s-13 fronts in my HR30, can't remember if the r30 tie rod ends fit or not. that may be a more pressing thing to look into.

shall do pretty sure ive organised with BC is street coilovers with 12 kgs at the front and 8 kgs in the rear!

[rsx84]

is this a daily driven car?? i think you'll get pretty sick of the ride being that stiff pretty quick...

[mr30walker]

it is my daily and im not to phased shall post pics of the conversion for everyone!
