BAD Handling DC2 Integra Type R

[freakygeek]

I understand, but even adrian from toda/tekno was telling me, put the tyre pressure higher... to 50 psi... don't get me wrong, he knows you and he said you know your stuff and you probably are making sense... I'm just not able to communicate the message across properly. I'll upload alignment sheet once i do it.

The only time Adrian would recommend this is for the dyno. He does this because it gives more consistent outputs between runs on the rollers.

I'm quite sure he would never recommend actually driving the car at these pressures.

I had a similar issue that the OP has. I too went to Adrian when he was at SAS (apparently owns another shop now? Can anyone confirm?) He said for me to DEFLATE my tires though. He said that 50PSI is wayyyyyyy to much after I told him about this post on here and confirmed that anything around 32 is optimal. I'm also not sure about the OP but what condition are your tires in? Are they bald etc? I just changed to some RSRs and haven't had an issue since listening to Adrian's advice.

EDIT: He also said that he would never recommend 50PSI for street driving - OP you sure you heard him correctly when you were talking to him?

Adrian is at tekno performance at eastern creek, he told me to leave my tyre pressures higher, this is because i told him about the side wall flex i have from the wrong sized tyres on the itr rim.
I've put on the stock swaybar and it has made a huge difference, but the coils are staying in for now.

Maybe i heard wrong...WTAC was a pretty loud event.. also, the tyres are about 2 years old now. I don't drive very aggressively, so they still have plenty of tread left.

could you describe the 'sidewall' flex? how much does it actually flex?

It's unusual... if i turn, i feel a good amount of lag before the car turns, as if the cars tyres are too high (which they are) the only way i resolved the issue was with putting more pressure into the tyres. I can try and come to the yearly meet, you can take it for a drive and you will know exactly what I'm talking about.

Simple solution. Get the right sized tyres on.

this keeps getting repeated, i highly doubt it is a 'solution'??

play with this to see how much 'extra' sidewall the 205/55 vs 195/55 adds- http://www.miata.net/garage/tirecalc.html (hint, it is ~6mm)

and we still have no alignment specs or ANY actual alignment info to go off...

i drive a Jazz with 185/60's RE002's on it and they do NOT have any excessive 'sidewall' flex that affects the handling (at 35psi cold).

and exhibit A is the pic of the OP tyres.

these show NO evidence of 'rolling over' due to lack of pressure:



or evidence of being driven on at all actually?

must be a reaaaaly old picture hey teggzy??? (date stamped 1 mth ago?)

I think i'll keep the coilovers in there for now and see how i go with the alignment.

wait... you still haven't got anyone to check the alignment?

I've got a few other priorities to sort out with my money before i can go and fix everything up, don't worry. Updates will be coming soon.

Also, i took that photo the day i uploaded it to club itr, the car gets driven roughly about 100km's a week.

Ill get back to you as soon as i can with the rest of the information.

A 205/55 wouldn't feel right on a DC2R wheel compared to a 195/55. I drove a DC2R on 205/50 (not as bad) and I didn't like the feel. It feels "squirmy" to me, the inputs are not rewarded with as sharp a response from the car.

Honda chose 195/55 for a reason on those particular wheels.

Well, i knew this from the day i bought my car, but i dont see the need in replacing tyres with 70+ percent tread still left, i did purchase a set of genuine jdm 16 inch dc2r wheels, which will get factory spec tyres on as soon as i get my funds sorted.

yeah, isn't it the same size tyre they chose to equip all the 1993-1999 Integra VTiR's with?

that said, i have never a run a 195/55-15 on any car, so i can't say much how it would feel...

You probably never had a 6" wide wheel either Tinks! hehe

The 205 on a 6.5 or 7" wheel would probably feel perfectly normal. A 205/45 on the 16x7 feels quite alright to me.

strangely enough, my 12 spoke Rota 16's are 6in wide, originally bought for a 83 Prelude (came stock with 5in rims, so had to stay legal with +1in) - then ran these rims on my DA6 & DC2 Integra's almost entirely with 205/50-16's (with Dunlop D01J, Falken Azenis, Dunlop Z1 [2 sets!]) to ensure i met the 84V load rating, (most 205/45's are <84 load rating - the Toyo T1R i ran being an exception).

but yeah, i've only ever run 205/50-15's on my 6.5in track rims...

but it comes down to tyre construction (and tyre condition/age/wear!) a fair bit when it comes to 'feel'...

in my experience, i find that i replace my tyres when they get old & hard, not when they reach the wear indicators... (just shows how few KM i put on my car - 75'000km in 11 years)
